Description

Technical Field

[0001] The invention belongs to the technical field of crane installation, and in particular relates to a device for adjusting the horizontality of a tower crane's foundation legs. Background Art

[0002] With the rapid development of society, the construction industry is constantly recovering, and the application of tower cranes is increasing. In the use of tower cranes, the foundation is particularly important, especially the horizontal control of the outriggers of tower cranes. If the levelness of the outriggers exceeds the deviation value during the establishment process, the entire foundation will have a poor use effect, which will affect the establishment and installation of the upper equipment, thus being invalidated and irreversible.

[0003] At present, when the foundation legs of tower cranes are leveled, most of them are leveled manually using a spirit level. However, this leveling method has certain disadvantages: first, the spirit level needs to be leveled before each use, and each user has different standards for leveling the equipment, which will cause errors to a certain extent. Second, there are errors in the instrument itself, that is, after the spirit level has been used for a long time, errors will also occur if the instrument is not calibrated. Third, for each use of the instrument, it is impossible to guarantee that the scale is absolutely horizontal or vertical, which will cause errors in readings. The errors in the above-mentioned links are constantly accumulated, which makes the level of the tower crane legs uneven. Of course, the calibration and adjustment of the instrument itself should be solved with a unified benchmark, but each The placement position during the first use is different, and its horizontal or verticality will be affected by the installation position of the equipment; in addition, the horizontality of the outrigger is an important reason for the verticality of the tower crane, and if the horizontality exceeds a certain error range, the tower crane installation work cannot be installed, which also means that the tower crane foundation is scrapped to a certain extent, causing great economic losses, while increasing time and high production costs. For this reason, we provide a tower crane foundation outrigger adjustment horizontality device with reasonable design, simple structure, convenient processing, and the ability to use itself as a reference to conveniently adjust the horizontal and vertical degrees, thereby assisting the installation of the foundation outrigger, fully ensuring the accuracy and stability of the established position, reducing errors, improving work progress, saving costs and meeting the use needs.

[0031] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0033] Examples, such as Figure 1 to Figure 12 As shown, a device for adjusting the level of a tower crane foundation leg comprises a level adjustment device 1, a tower crane leg body is arranged on the outer side of the level adjustment device 1, and the tower crane leg body comprises a mounting frame 3, which is used to ensure the use strength of the tower base leg body 2 established, and a lifting leg 4 is arranged at the lower corner of the mounting frame 3, which can be adaptively adjusted according to different use requirements, especially to ensure that it has a good level, and an adapting support component 5 is arranged between the two lifting legs 4 on the same side, which plays an auxiliary supporting role in the establishment of the lifting legs 4 and improves stability; the level adjustment device 1 comprises a frame 6, and a stabilizing leg 7 for supporting and stabilizing the position of the equipment is arranged on the lower outer side of the frame 6, and an adjusting leg 8 for conveniently adjusting the level is arranged at the corner of the frame 6, and the adjusting leg 8 is controlled and adjusted, especially the vertical height of the corner is adjusted, and acts on the reference positioning component 14, so that it can give full play to the reference positioning effect and ensure the smooth progress of subsequent processing work. A support frame 9 designed in an H shape is arranged above the frame body 6, and a horizontality observation device 10 is arranged above the geometric center of the support frame 9, which uses the principle of a communicating vessel to reduce the possibility of errors in the device itself and ensure accuracy. A positive and negative synchronous moving component 11 is arranged on one side of the support frame 9, which can drive the device to synchronously adjust in opposite directions or towards each other in the horizontal direction to provide convenient conditions. A sliding component is arranged on the other side of the support frame 9, which functions to improve the smoothness of the movement of the positive and negative synchronous adjustment component 13 in the horizontal direction. The output end of the positive and negative synchronous moving component 11 is provided with a positive and negative synchronous adjustment component 13, and straddles the sliding component, which can drive the device to move in opposite directions or towards each other in the longitudinal direction. The output end of the positive and negative synchronous adjustment component 13 is provided with a reference positioning component 14 with verticality and horizontality detection functions, which, under the action of the adjusting leg 8, establishes a reference for the installation position of the tower base leg body 2, so as to ensure the stability and accuracy of the establishment of the tower base leg body 2 and meet the use requirements;

[0034] Further description is as follows: according to the installation position of the tower base leg body 2, the position of the level adjustment device 1 is adjusted, and then the level observation device 10 is opened to allow liquid to be injected into the liquid level tube 145, and then according to the specifications of the tower base leg body 2 to be established, the position of each reference positioning component 14 is pre-adjusted, and then the operation of the adjustment legs 8 on the four corners is controlled respectively by the liquid level gauge 144 on the reference positioning component 14 and the liquid level in the liquid level tube 145, that is, the operation of the first cylinder 83 and the second cylinder 86 is controlled, and the cooperation between the two is utilized to make the lower end of the adjustment leg 8 contact and support the ground at the installation location, Observe the liquid level in the reference positioning assembly 14 in real time until the liquid level gauges 144 in the four groups of reference positioning assemblies 14 are horizontal, that is, their verticality is determined, the indications of the four groups of liquid level tubes 145 are unified, their vertical heights are also determined, and then the horizontality is determined. In this way, the tower base leg body 2 can be set up and installed according to the position of the reference positioning assembly 14 in the adjusted horizontality adjustment device 1, and its horizontality and verticality are determined. After the setting is completed, the horizontality adjustment device 1 is evacuated, which can meet the needs of setting up the tower base leg body 2 at different positions under different working conditions. The device is simple and convenient to operate and has strong functionality.

[0035] In the above process: through the set level adjustment device 1, the set stable legs 7 can be used to achieve smooth movement and stable placement of the equipment, and the set adjustable legs 8 can be used to adaptably adjust the corners of the equipment, especially the reference positioning component 14 is adjusted to a suitable position, ensuring the convenient establishment of the positioning reference, and providing a prerequisite for the installation of the tower base leg body 2; through the set level observation device 10 and the reference positioning component 14, the former uses the principle of the communicating vessel to locate the height of the tower base leg body 2, that is, to ensure its levelness, and the latter is under the action of the level adjustment device 1. The verticality of the tower base leg body 2 is limited, which greatly improves the accuracy of the tower base leg body 2 and meets the use requirements; the device is reasonably designed, simple in structure, easy to process, and can use itself as a reference to conveniently adjust the horizontal and vertical degrees, thereby playing an auxiliary role in the installation of the foundation legs, fully ensuring the accuracy and stability of the position where it is established, reducing errors, improving the work process, saving costs and meeting the use requirements.

[0036] In order to effectively complete the convenient adjustment of the height of the lifting legs 4, the lifting legs 4 include an upper bracket 41, and a mounting beam 15 arranged diagonally is arranged above the upper bracket 41. A lower bracket 42 is sleeved in the upper bracket 41, and a reinforcing plate 43 is arranged at the lower end of the lower bracket 42. A fine-tuning component 44 is arranged on the reinforcing plate 43. Specifically, the lower bracket 42 can be moved and adjusted in the vertical direction relative to the upper bracket 41. For the fixation between the adjusted upper bracket 41 and the lower bracket 42, bolts can be used to limit them, that is, the bolts pass through the upper bracket 41 and the lower bracket 42, and are locked with nuts. Of course, this structure is not shown, but it is an existing mature and conventional technical means, and the details are not repeated. Of course, the lifting legs 4 can also be adaptively selected, such as using hydraulic pressure to control the lifting and adjustment of the equipment, so that the degree of automation in the process of adjusting the height of the legs can be improved, and labor costs can be saved. The above is also a conventional technical means of existing cranes, and the details are not repeated. Further, in order to fully improve the stability of the establishment of the lifting legs 4 The adaptable support assembly 5 includes a horizontal plate 51, which is set on two upper brackets 41 on the same side. A connecting seat 52 is set below the lower bracket 42. A first two-way telescopic rod 53 is set on one side of the connecting seat 52, and a second two-way telescopic rod 54 is set on the other side of the connecting seat 52. The two second two-way telescopic rods 54 are arranged in a mirror image, and one end thereof is connected to the end of the first two-way telescopic rod 53, and the other end is connected to the horizontal plate 51. For the selected two-way telescopic rod, both ends of the two-way telescopic rod can be moved and adjusted relative to its geometric center. Of course, it also has a certain damping property. When the height of the lifting leg 4 is adjusted according to different usage requirements, the two ends of the first two-way telescopic rod 53 and the second two-way telescopic rod 54 can be adaptively stretched or contracted. In particular, based on the fact that the vertical erection position of the lifting leg 4 will not change significantly, the establishment of the adaptable support assembly can promote the stability between the lifting legs 4 on the same side, thereby ensuring the use effect of the tower base leg body 2.

[0037] In order to make the position of the horizontal adjustment device 1 finely adjusted in the vertical direction, the stabilizing leg 7 includes a mounting plate 71, a telescopic shock-absorbing rod 72 is arranged above the two mounting plates 71, and a cross bar 721 is arranged at the end of the telescopic shock-absorbing rod 72. Of course, a key-shaped groove is also provided on the outer side of the support plate 75 to limit the moving direction of the cross bar 721. A frame plate 73 is arranged below the two mounting plates 71, and a pulley 74 is arranged at one end of the frame plate 73. A support plate 75 is provided on the inner side, and a torsion spring is also provided on the shaft where the frame plate 73 and the support plate 75 rotate. One end of the torsion spring is located on the inner side of the support plate 75, and the other end is engaged with the corner of the frame plate 73. A limiting groove 751 designed in an L shape is provided in the support plate 75 away from the pulley 74, and the cross bar 721 is limited. A positioning groove 752 is provided on the other side of the support plate 75. A snap-fit ​​sub-button 76 is provided on the support plate 75 on one side of the positioning groove 752, and the snap-fit ​​sub-button 76 is connected with the snap-fit ​​sub-button The inner side of the frame plate 73 corresponding to the sub-buckle 76 is provided with a snap-fitting female buckle 77, which is specifically described as follows: when the level adjustment device 1 needs to be moved, the cross bar 721 is in the limit groove 751, and the snap-fitting sub-buckle 76 and the snap-fitting female buckle 77 cooperate together. In this state, the stabilizing leg 7 can be smoothly moved and adjusted, and can be moved to adapt to different terrains. It has strong functionality. When it is necessary to fine-tune the height of the level adjustment device 1, first press one side of the support plate 75 downward, and make the cross bar 721 of the telescopic shock-absorbing rod 72 disengage from the limit groove 751, and then move the cross bar 721 to the rear side relative to the key groove. When it approaches the positioning groove 752, the support plate 75 is reset and ensure that the cross bar 721 corresponds to the positioning groove 752. At the same time, the snap-fitting sub-buckle 76 and the female buckle are snapped to complete the fine adjustment of its vertical height, thereby increasing the functionality of the device and providing convenient conditions for the device to cross obstacles during travel.

[0038] In order to effectively complete the adjustment of the position of the horizontal adjustment device 1 and conveniently adjust the position of the reference positioning assembly 14 in the horizontal and vertical directions, thereby providing a reliable reference for the subsequent installation and establishment of the tower base leg body 2, further, the operation of the adjustment leg 8 is set up to imitate the spider leg, that is, the height can be conveniently adjusted in the vertical direction. The adjustment leg 8 includes a mounting seat 81, a rotating plate 82 is arranged above the mounting seat 81, an ear seat 821 is arranged above the rotating plate 82, a first cylinder 83 is arranged on the ear seat 821, a rotating rod 84 is arranged on the lower side of the rotating plate 82, a rotating seat 85 is arranged on the rotating rod 84, and the upper part of the rotating rod 84 is connected to the output end of the first cylinder 83, a second cylinder 86 is arranged below the rotating rod 84, and its output end is connected to the lower part of the rotating seat 85, and a telescopic leg 87 is arranged on the rotating seat 85 A rotating support seat 871 is provided below the telescopic leg 87, which is specifically described as follows: the extension or contraction of the first cylinder 83 can conveniently adjust the erection range of the adjustment leg 8, especially the opening and closing angle of the telescopic leg 87 and the convenient adjustment of the rotating plate 82 in the vertical plane. The second cylinder 86 can cooperate with the first cylinder 83 to complete the adjustment of the position of the adjustment leg 8. When it is necessary to adjust the position of each corner of the horizontal adjustment device 1, especially the position of the reference positioning component 14, the first cylinder 83 and the second cylinder 86 are controlled to extend or contract, and the change in their angles is used to achieve convenient adjustment of the equipment height. Of course, the four groups of adjustment legs 8 can be adjusted synchronously or separately until the reference positioning component 14 is adjusted to a suitable position. The operation is simple and convenient, and the use functionality is strong.

[0039] In order to effectively complete the horizontality of the position of the reference positioning component 14 and make multiple legs at the same height, the horizontality observation device 10 includes a liquid storage tank 101, which is set up above the support frame 9 to provide a prerequisite for the subsequent leveling work. A liquid filling port 102 is set above the liquid storage tank 101, a vacuum pump 103 is set on one side of the liquid filling port 102, a pressure relief valve 104 is set on one side of the vacuum pump 103, and a liquid infusion pipe 105 is set below the liquid storage tank 101, wherein a one-point four-valve body can be set up below the liquid storage tank 101, that is, the upper port is connected to the liquid storage tank 101, and the lower four-way valve body is connected to the lower liquid storage tank 101. The ports are respectively connected with infusion pipes 105 and are connected with the liquid level pipe 145. When the reference positioning assembly 14 is adjusted to a suitable position, the one-point four valve body is opened, so that the liquid can smoothly enter the liquid level pipe 145 through the infusion pipe 105. The principle of the communicating vessel is used to facilitate the subsequent height adjustment of the lifting legs 4. A double-ear hook 106 is provided above the liquid storage tank 101 and is adapted to be engaged with the mounting beam 15. Its function is to make the establishment of the component more stable by using the establishment of the double-ear hook 106 after the horizontal observation device 10 is adjusted to a suitable position. The specific description is as follows: the vacuum pump 103 is powered by a lithium battery pack Electric, its main function is to draw the liquid in the pipeline back to the liquid storage tank 101, so as to realize the recycling of the liquid and save costs. Further, the liquid storage tank 101 is filled with liquid, such as colored antifreeze, which is convenient for people to observe on the one hand, and on the other hand, it can take into account the supply use environment. That is to say, when carrying out the reference positioning work, first open the level observation device 10 to allow the liquid to flow into the liquid level tube 145, and then adjust the position of the frame 6 and the level observation device 10 under the action of the adjustment leg 8, especially to ensure that the liquid level gauge 144 in the reference positioning component 14 determines the rise The height of the lifting leg 4 is determined by ensuring that the lowering leg 4 is absolutely vertical in the horizontal direction and that the indications of multiple liquid level tubes 145 are the same. Subsequently, the tower base leg body 2 is installed and established according to the position of the reference positioning assembly 14. After the installation work is completed, the vacuum pump 103 is controlled to operate to draw back the liquid in the liquid level tube 145. After the liquid is completely drawn back, the valve body is closed and the device is ready for next use. This greatly improves the functionality of the device and its adaptability. At the same time, the working principle mainly uses the principle of communicating vessels, which is convenient and intuitive to observe. To a certain extent, there is no problem of inherent errors in instruments and measuring tools, and the use effect is remarkable.
