Description
Technical Field
[0001] The present invention relates to the technical field of hoisting equipment for foundation pits, and particularly to an adjusting device for hoisting foundation pit equipment. Background Art
[0002] In the field of equipment installation, it is often encountered that some equipment needs to be installed in a lower-level pit foundation, or scenarios such as the assembly of the inner core and the outer shell of large equipment. In such assemblies, the assembly gaps between the equipment or components to be installed and the pit foundation and the equipment outer shell are very narrow. When lowering the components or equipment to be assembled into the pit or the equipment housing, it is necessary to protect them very carefully and adjust the central positions of the components to be assembled and the pit and the equipment housing at any time to ensure relative centering, so that the assembly gaps can be uniform and avoid damage to the equipment body caused by collisions during assembly.
[0003] Generally, when hoisting such equipment, often the rigger and the assembly worker control the sling by reducing the action rate, constantly manually detecting the surrounding gaps and manually intervening in the traction and other methods to prevent the center from shifting during the assembly process, resulting in unilateral gap rubbing and damaging the equipment. Summary of the Invention
[0004] The purpose of the present invention is to solve the disadvantages existing in the prior art, and to propose an adjusting device for hoisting foundation pit equipment. Its advantages are as follows: This patent designs a tooling for automatically adjusting the gap. The tooling is installed on the edge of the equipment to be assembled, and contacts the foundation pit wall and the equipment housing through the extended guide wheels, thereby controlling the gap. When the equipment deviates to one side, the oil pressure and the piston in the system start to work, generating a reverse intervention, prompting the equipment to return to the central position, avoiding the touch of the edge gap, and improving the stability and safety of the hoisting of the equipment to be assembled.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] An adjusting device for hoisting foundation pit equipment includes four hydraulic mechanisms and the equipment to be assembled. The four hydraulic mechanisms are respectively fixedly installed at the four corners of the top of the equipment to be assembled. The tails of the four hydraulic mechanisms are all fixedly installed with hydraulic oil pipes, and the ends of the four hydraulic oil pipes far from the hydraulic mechanisms are connected to the same oil circuit distributor.
[0007] By the above technical solutions: During use, the hydraulic mechanisms are installed at the four corners of the edge of the top of the equipment to be assembled, contact the foundation pit wall and the equipment housing, thereby controlling the gap. When the equipment deviates to one side, the oil pressure and the piston in the system start to work, generating a reverse intervention, prompting the equipment to return to the central position, avoiding the touch of the edge gap.
[0008] The present invention is further configured such that the hydraulic mechanism includes an outer cylinder body. A stepped groove is formed inside the outer cylinder body, and a piston body is slidably connected to the large-mouth end of the groove. The cross-section of the piston body at the position inside the groove is stepped, and the surface of the piston body is fitted to the groove. A piston buffer spring is fixedly installed between the piston body and the large-mouth end of the groove. A tail end cover is fixedly installed at the end of the outer cylinder body away from the piston body.
[0009] A chute is formed at the small-mouth end of the piston body close to the groove. A central rod is fixedly installed on the inner wall of the end of the groove away from the piston body, and the central rod is inserted into the inner wall of the chute. An internal oil passage is formed at the end of the central rod away from the piston body, and the internal oil passage is communicated with a hydraulic oil pipe. Through holes corresponding to the stepped cross-section of the groove are formed at the top of the internal oil passage. Oil guiding holes communicated with the chute are formed at the stepped cross-section position of the piston body.
[0010] By the above technical solutions: Specifically, when the extension amount of the piston body of one of the hydraulic mechanisms is greater than the extension and contraction amount of the piston body of the hydraulic mechanism at its opposite end, at this time, the number of through holes and oil guiding holes that are mutually conducted above the oil passage inside this hydraulic mechanism is more, and more stepped surfaces on the groove will store oil. Furthermore, the oil pressure of this hydraulic mechanism is less than the oil pressure of the hydraulic mechanism at its opposite end. Then the piston body will contract to ensure the relative oil pressure balance, achieving the effect of adjusting the stability of the equipment.
[0011] The present invention is further configured such that a connecting mechanism is fixedly installed at the end of the piston body away from the tail end cover, and a buffer mechanism is fixedly installed at the end of the connecting mechanism away from the piston body.
[0012] By the above technical solutions: The buffer mechanism buffers the hydraulic mechanism and the inner wall of the foundation pit, improving the stability and safety of the hoisting.
[0013] The present invention is further configured such that the connecting mechanism includes a connecting rod fixedly installed at one end of the piston body. A sleeve is sleeved at the end of the connecting rod away from the piston body, and a transverse buffer spring is fixedly installed between the sleeve and the connecting rod.
[0014] By the above technical solutions: The transverse buffer spring realizes the transverse buffering between the equipment to be assembled and the edge of the foundation pit during hoisting, improving the stability and safety of the hoisting.
[0015] The present invention is further configured such that the buffer mechanism includes two support rods. One ends of the two support rods are respectively hinged to the top and bottom of the end of the sleeve away from the connecting rod. A longitudinal buffer spring is fixedly installed at the middle position between the two support rods. A support plate is hinged at the end of the support rod away from the sleeve, and clamping plates are fixedly installed at both ends of the support plate. A rotating roller is rotatably arranged between the two clamping plates.
[0016] Through the above technical solutions: Since the inner wall surface of the foundation pit is uneven, during the process of lowering the equipment to be assembled, there will be longitudinal wear between the hydraulic mechanism and the inner wall surface of the foundation pit. Therefore, through the longitudinal buffer spring, the wear between the hydraulic mechanism and the inner wall surface of the foundation pit can be effectively reduced, improving the stability and safety of hoisting.
[0017] The present invention is further configured such that an installation groove is formed at one end of the clamping plate close to the rotating roller, and peripheral buffer springs are fixedly installed on the inner walls around the installation groove. One end of each peripheral buffer spring away from the inner wall of the installation groove is fixedly installed with the same installation plate, and a rotating shaft is rotatably installed between one end of the installation plate close to the rotating roller and the rotating roller.
[0018] Through the above technical solutions: Since the inner wall surface of the foundation pit is uneven during the hoisting process of the equipment to be assembled, the rotating roller cannot effectively fit the inner wall of the foundation pit. Through the peripheral buffer springs, the rotating roller can be made to fully fit the inner wall of the foundation pit, improving the stability and safety of hoisting.
[0019] The present invention is further configured such that a protective sleeve is fixedly installed at the middle position between the two support rods, and the protective sleeve is sleeved outside the longitudinal buffer spring.
[0020] Through the above technical solutions: The protective sleeve protects the longitudinal buffer spring, preventing stones and other sundries from entering the longitudinal buffer spring and jamming it, affecting its buffering effect.
[0021] The present invention is further configured such that an installation base is fixedly installed at the bottom of the hydraulic mechanism, and the bottom of the installation base is fixedly connected to the top of the equipment to be assembled.
[0022] Through the above technical solutions: The installation base connects the hydraulic mechanism and the equipment to be assembled, with high stability and convenient disassembly and assembly.
[0023] The beneficial effects of the present invention are as follows:
[0024] 1. For the adjustment device for hoisting equipment in the foundation pit, during use, the hydraulic mechanism is installed at the four corner edges of the top of the equipment to be assembled, contacting the inner wall of the foundation pit hole and the equipment shell, thereby controlling the gap. When the equipment deviates to one side, the oil pressure and piston in the system start to work, generating a reverse intervention to prompt the equipment to return to the central position and avoid the contact of the edge gap.
[0025] 2. For the adjusting device for hoisting foundation pit equipment, the extension amount of the piston body of one hydraulic mechanism is greater than that of the piston body of the hydraulic mechanism at its opposite end. At this time, the number of through holes and oil guiding holes that are interconnected above the oil path inside the hydraulic mechanism is large, and there will be more stepped surfaces for oil storage on the groove. Furthermore, the oil pressure of this hydraulic mechanism is less than that of the hydraulic mechanism at its opposite end. As a result, the piston body will contract to ensure the balance of the relative oil pressure, achieving the effect of adjusting the stability of the equipment.
[0026] 3. For the adjusting device for hoisting foundation pit equipment, since the inner wall surface of the foundation pit is uneven, during the process of lowering the equipment to be assembled, there will be longitudinal wear between the hydraulic mechanism and the inner wall surface of the foundation pit. Therefore, through the longitudinal buffer spring, the wear between the hydraulic mechanism and the inner wall surface of the foundation pit can be effectively reduced, improving the stability and safety of hoisting.
[0027] 4. For the adjusting device for hoisting foundation pit equipment, during the hoisting process of the equipment to be assembled, since the inner wall surface of the foundation pit is uneven, the rotating roller cannot effectively fit the inner wall of the foundation pit. Through the surrounding buffer springs, the rotating roller can be made to fully fit the inner wall of the foundation pit, improving the stability and safety of hoisting.

[0036] The embodiments of this patent will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain this patent and should not be construed as a limitation to this patent.

[0038] In the description of this patent, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "coupling", "setting" should be understood in a broad sense. For example, it can be fixedly connected and set, or detachably connected and set, or integrally connected and set. For those of ordinary skill in the art, the specific meanings of the above terms in this patent can be understood according to specific circumstances.
[0039] Referring to Figures 1-6 , an adjusting device for hoisting a foundation pit equipment, includes four hydraulic mechanisms 2 and an equipment to be assembled 4. The four hydraulic mechanisms 2 are respectively fixedly installed at the four corners of the top of the equipment to be assembled 4. The tail ends of the four hydraulic mechanisms 2 are all connected with hydraulic oil pipes 3 through bolts. One end of the four hydraulic oil pipes 3 far away from the hydraulic mechanisms 2 is connected to the same oil circuit distributor 5.
[0040] Specifically, the hydraulic mechanism 2 includes an outer cylinder body 10. A stepped groove is formed inside the outer cylinder body 10. A piston body 8 is slidably connected to the large-mouth end of the groove. The cross-section of the piston body 8 at the position inside the groove is stepped, and the surface of the piston body 8 is arranged in fit with the groove. A piston buffer spring 9 is connected between the piston body 8 and the large-mouth end of the groove by bolts. A tail end cover 15 is connected to the end of the outer cylinder body 10 away from the piston body 8 by bolts. A chute is formed at the small-mouth end of the piston body 8 close to the groove. A central rod 13 is connected to the inner wall of the groove away from the piston body 8 by bolts, and the central rod 13 is inserted into the inner wall of the chute. An internal oil passage 14 is formed at the end of the central rod 13 away from the piston body 8, and the internal oil passage 14 is communicated with the hydraulic oil pipe 3. Through holes corresponding to the stepped cross-section of the groove are formed at the top of the internal oil passage 14. Oil guide holes communicated with the chute are formed at the stepped cross-section position of the piston body 8. When the extension amount of the piston body 8 of one of the hydraulic mechanisms 2 is greater than the extension and contraction amount of the piston body 8 of the hydraulic mechanism 2 at the opposite end, at this time, the number of through holes and oil guide holes that are mutually conducted above the internal oil passage of this hydraulic mechanism 2 is more, and more stepped surfaces on the groove store oil. Furthermore, the oil pressure of this hydraulic mechanism 2 is less than the oil pressure of the hydraulic mechanism 2 at the opposite end. Then, the piston body 8 will contract to ensure the relative oil pressure balance, achieving the effect of adjusting the stability of the equipment.
[0041] Furthermore, a connecting mechanism 7 is connected to the end of the piston body 8 away from the tail end cover 15 by bolts. A buffer mechanism is connected to the end of the connecting mechanism 7 away from the piston body 8 by bolts. The buffer mechanism buffers the hydraulic mechanism 2 and the inner wall of the foundation pit 1, improving the stability and safety of the hoisting.
[0042] Specifically, the connecting mechanism 7 includes a connecting rod 19 fixedly installed at one end of the piston body 8. A sleeve 20 is sleeved on the end of the connecting rod 19 away from the piston body 8. A transverse buffer spring 18 is connected between the sleeve 20 and the connecting rod 19 by bolts. The buffer mechanism includes two support rods 17. One ends of the two support rods 17 are respectively hinged to the top and bottom of the end of the sleeve 20 away from the connecting rod 19. A longitudinal buffer spring 21 is connected between the middle positions of the two support rods 17 by bolts. A support plate is hinged to the end of the support rod 17 away from the sleeve 20, and clamping plates 16 are connected to both ends of the support plate by bolts. A rotating roller 6 is rotatably arranged between the two clamping plates 16. The transverse buffer spring 18 realizes the transverse buffering between the equipment 4 to be assembled and the edge of the foundation pit 1 during hoisting, improving the stability and safety of the hoisting. Since the inner wall surface of the foundation pit 1 is uneven, when the equipment 4 to be assembled descends, longitudinal abrasion will occur on the surfaces of the hydraulic mechanism 2 and the inner wall of the foundation pit 1. Therefore, through the longitudinal buffer spring 21, the abrasion on the surfaces of the hydraulic mechanism 2 and the inner wall of the foundation pit 1 can be effectively reduced, improving the stability and safety of the hoisting.
[0043] One end of the clamping plate 16 close to the rotating roller 6 is provided with an installation groove, and four surrounding buffer springs 23 are connected to the inner walls around the installation groove by bolts. One end of each of the four surrounding buffer springs 23 away from the inner wall of the installation groove is connected to the same installation plate 24 by bolts. One end of the installation plate 24 close to the rotating roller 6 and the rotating roller 6 are connected by a bearing to a rotating shaft 25. Since the inner wall surface of the foundation pit is uneven during the hoisting process of the equipment 4 to be assembled, the rotating roller 6 cannot effectively fit the inner wall of the foundation pit. Through the four surrounding buffer springs 23, the rotating roller 6 can fully fit the inner wall of the foundation pit, improving the stability and safety of hoisting.
[0044] It is worth mentioning that a protective sleeve 22 is connected to the middle position between the two support rods 17 by bolts, and the protective sleeve 22 is sleeved outside the longitudinal buffer spring 21. The protective sleeve 22 protects the longitudinal buffer spring 21 to prevent stones and other sundries from entering the longitudinal buffer spring 21 and jamming it, affecting its buffering effect.
[0045] The bottom of the hydraulic mechanism 2 is connected to an installation base 11 by bolts, and the bottom of the installation base 11 is fixedly connected to the top of the equipment 4 to be assembled. The installation base 11 connects the hydraulic mechanism 2 and the equipment 4 to be assembled, with high stability and convenient disassembly and assembly.
[0046] Working principle: During use, the hydraulic mechanism is installed at the four corner edges of the top of the equipment 4 to be assembled, in contact with the wall of the foundation pit 1 and the equipment housing, so as to control the gap. When the equipment deviates to one side, the oil pressure and the piston in the system start to work, generating a reverse intervention to prompt the equipment to return to the central position and avoid the contact of the edge gap.
[0047] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent replacements or changes, should be covered by the protection scope of the present invention.
