[0002] In engineering technology fields such as buildings and bridges, steel support is a common support structure. The main components of steel support are top rods and support rods. The two rods are connected together and fixed and adjusted by pins. The height of the steel support needs to be adjusted according to the size of the structure. Among them, the top rod is the main load-bearing component of the steel support, which is used to bear the upper load and transfer it to the foundation. The top rod is usually made of high-strength steel and has good bending stiffness and compressive resistance. It is used to connect the top rod with the foundation or other supporting components to play a supporting and stabilizing role.

[0003] The existing structural adjustment method requires construction workers to stand at a high place and manually insert and pull out the top rod. When the required height range is reached, the fixed pins are installed in line with the pin holes on the inner and outer tubes, and then the upper screw is used for fine adjustment to reach the required height. This adjustment method requires construction workers to work at high altitudes, which poses a safety hazard; the top rod is heavy, which makes the operation time-consuming and laborious; the operation steps are cumbersome and the work efficiency is low. Summary of the invention

[0019] The following is a clear and complete description of the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0020] First, the terms that may be used in this article are explained as follows:

[0021] The term “and / or” means that either or both of them can be realized at the same time. For example, X and / or Y means both “X” or “Y” and “X and Y”.

[0022] The terms "include", "comprises", "contains", "has" or other descriptions with similar semantics should be interpreted as non-exclusive inclusion. For example, including certain technical feature elements (such as raw materials, components, ingredients, carriers, dosage forms, materials, dimensions, parts, components, mechanisms, devices, steps, procedures, methods, reaction conditions, processing conditions, parameters, algorithms, signals, data, products or products, etc.) should be interpreted as including not only certain technical feature elements explicitly listed, but also other technical feature elements known in the art that are not explicitly listed.

[0023] The term "consisting of..." means excluding any technical feature elements not explicitly listed. If this term is used in a claim, it will make the claim closed, so that it does not contain technical feature elements other than the technical feature elements explicitly listed, except for the conventional impurities related to them. If this term only appears in a clause of a claim, it only limits the elements explicitly listed in the clause, and the elements recorded in other clauses are not excluded from the overall claim.

[0024] The term "parts by mass" refers to the mass ratio relationship between multiple components. For example, if it is described that component X is x parts by mass and component Y is y parts by mass, then the mass ratio of component X to component Y is x:y. 1 part by mass can represent any mass, for example, 1 part by mass can be represented as 1 kg or 3.1415926 kg. The sum of the parts by mass of all components is not necessarily 100 parts, but can be greater than 100 parts, less than 100 parts or equal to 100 parts. Unless otherwise specified, the parts, proportions and percentages described herein are all measured by mass.

[0025] Unless otherwise specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example: it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this article can be understood according to specific circumstances.

[0026] When concentration, temperature, pressure, size or other parameters are expressed in the form of a numerical range, the numerical range should be understood to specifically disclose all ranges formed by the pairing of any upper limit, lower limit, and preferred value in the numerical range, regardless of whether the range is explicitly stated; for example, if a numerical range of "2 to 8" is stated, the numerical range should be interpreted as including ranges such as "2 to 7", "2 to 6", "5 to 7", "3 to 4 and 6 to 7", "3 to 5 and 7", "2 and 5 to 7", etc. Unless otherwise specified, the numerical ranges stated herein include both their end values ​​and all integers and fractions within the numerical range.

[0027] The orientation or position relationship indicated by terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc. are based on the orientation or position relationship shown in the drawings and are only for the convenience and simplification of description, and do not explicitly or implicitly indicate that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation of this document.

[0028] The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] like Figure 1 and 2As shown, a lifting and adjusting steel support device comprises a sleeved support inner tube 2 and a support outer tube 4; the support inner tube 2 is provided with a plurality of evenly distributed radial inner adjustment pin holes 21 along the axial direction; the support outer tube 4 is provided with a radial outer positioning pin hole 41; the latch pin 7 is fixed and adjusted through one of the outer positioning pin hole 41 and the radial inner adjustment pin hole 21 for supporting and adjusting the steel support device.

[0030] like Figure 3 As shown, in this example, the lifting and adjusting steel support device also includes a lifting screw mechanism and an adjusting drive mechanism 5; the lifting screw mechanism includes a lifting screw 3 and a fixing nut 6; the fixing nut 6 is fixed to the lower end of the support inner tube 2, and can be a welded structure, and the lifting screw 3 and the fixing nut 6 are connected in cooperation; here, the lifting screw 3 and the fixing nut 6 constitute a fixing nut-sliding screw mechanism. The threaded connection between the lifting screw 3 and the fixing nut 6 needs to meet the self-locking requirement.

[0031] like Figure 4 As shown, the adjustment drive mechanism 5 includes a driving bevel gear 51, a driven bevel gear 52, a driven gear shaft 53, an adjustment gear shaft 54 ​​and a housing 55; the housing 55 is fixed below the supporting outer tube 4, and the specific housing 55 is welded by multiple end plates, and a connecting flange is provided below the supporting outer tube 4 to be connected and fixed with the end plate flange above the housing 55. The driven gear shaft 53 is arranged at the lower end of the lifting screw 3, and the driven gear shaft 53 extends into the housing 55. The specific lifting screw 3 and the driven gear shaft can be coaxially connected or an integrated structure. The driven bevel gear 52 is installed on the driven gear shaft 53, and the shaft system structure such as the end face thrust bearing 57 and the shaft sleeve 56 are also included here. The design and connection method of these structures are well-known technologies and will not be repeated. The adjustment gear shaft 54 ​​is arranged horizontally below the driven bevel gear 52 and is installed on the housing 55, specifically installed on the end plates on both sides. The end plates of the housing 55 are used for fixing and limiting. Of course, it includes structures such as roller bearings, and the design and connection methods of these structures are well-known technologies and will not be repeated. The driving bevel gear 51 is installed on the adjusting gear shaft 54 ​​and meshes with the driven bevel gear 52; the adjusting gear shaft 54 ​​is rotated to drive the lifting screw 3 to rotate through the meshing two gears, driving the fixing nut 6 and the supporting inner tube 2 to move up and down, and adjusting the supporting height of the steel support device.

[0032] In this example, if Figure 5 As shown, a fine-tuning screw mechanism 1 is also provided above the support inner tube 2; the fine-tuning screw mechanism 1 includes a fine-tuning nut 11 and a fine-tuning screw 12; the fine-tuning nut 11 is installed at the lower end of the fine-tuning screw 12 and then extends into the support inner tube 2, the fine-tuning nut 11 is clamped at the upper end of the support inner tube 2, and the fine-tuning nut 11 is rotated to adjust the height of the screw 12 up and down to fine-tune the support height of the steel support device. Here, the upper end of the fine-tuning screw 12 is also connected to a top plate 8, which contacts the upper object to be supported to increase the contact area.

[0033] How it works

[0034] A fixing nut 6 is welded to the lower end of the support inner tube 2, and the upper end of the lifting screw 3 is screwed into the support inner tube 2 through the fixing nut 6, so that the support inner tube 2 and the lifting screw 3 can be firmly assembled together; then the lower end of the lifting screw 3 is inserted into the support outer tube 4, and the driven gear shaft 53 at the lower end of the lifting screw 3 is inserted into the shell 55, and the driven bevel gear 52 is installed on the driven gear shaft 53; then the driving bevel gear 51 and the adjusting gear shaft 54 ​​are installed; then the lower end of the support outer tube 4 is connected to the shell 55 through a flange connection, and the fine-tuning screw mechanism 1 is placed on the support inner tube 2 from the upper end.

[0035] When in use, firstly, the support height of the steel support device is roughly adjusted and fixed by changing the plug pin 7 and inserting it into one of the outer positioning pin hole 41 and the radial inner adjustment pin hole 21; then, the adjusting gear shaft 54 ​​is turned with a wrench, and the driven gear shaft 53 and the lifting screw 3 are driven to rotate through the engagement of the active bevel gear 51 and the driven bevel gear 52, and the fixed nut-sliding screw mechanism formed by the lifting screw 3 and the fixing nut 6 drives the support inner tube 2 fixed with the fixing nut 6 to move up and down, so as to further adjust the support height of the steel support device and position it through the self-locking position of the thread; finally, the support height of the steel support device is fine-tuned by rotating the fine-tuning nut 11 to make the fine-tuning screw 12 move up and down.

[0036] It can be seen that the lifting and adjusting steel support device of the present invention can realize the lifting and adjusting of the steel support device by meshing the bevel gears with only simple tools, which is simple to operate and efficient in construction, saving time and labor; it does not require high-altitude operations and can be completed on the ground, thereby improving safety. It has a simple structure, is easy to assemble, has strong adaptability, and is widely used; it can save labor costs and greatly improve work efficiency.

Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
