Description

Technical Field

[0001] The invention relates to the technical field of elevator guide rails, in particular to an elevator guide rail frame for building construction. Background Art

[0002] The core function of the guide frame is to provide support and guidance for the operation of the elevator. It is composed of several standard sections combined by bolts. The standard section is usually welded from four columns and multiple beams. The elevator cage runs up and down along the main chord of the guide frame through four sets of guide rollers. Lubricating oil is often applied to the gear rack of the transmission structure to ensure the stable operation of the elevator. However, during the operation of the cage, part of the oil is squeezed out and flows along the surface of the rack, forming oil accumulation at the welding point of the guide frame beam. Certain corrosion and rust will occur over a long period of time. Corrosion will expand the original weld defects such as pores and slag inclusions, resulting in uneven local stiffness, which may cause the overall tilt of the guide frame. There are certain safety hazards, and when a single column or beam is damaged, the overall standard section needs to be replaced, which will cause certain waste. Summary of the invention

[0005] As a further optimization scheme of the present invention, the clamping assembly includes a movable vertical rod slidably arranged on the inner side of the supporting column, the movable vertical rod passes through the connecting seats located in the upper two groups and is slidably connected thereto, a movable disc fixed to the movable vertical rod is arranged on the top of the connecting seat, and the movable disc is slidably connected to the inner side of the supporting column.

[0006] As a further optimization scheme of the present invention, a limiting sleeve is integrally formed at the bottom of the supporting column. When several standard section frames are stacked, the limiting sleeve at the bottom of the upper supporting column is inserted into the inner side of the top of the lower supporting column, and the limiting sleeve is in contact with the topmost movable disc on the inner side of the supporting column.

[0007] As a further optimization scheme of the present invention, a connecting pin is fixed to the bottom of the movable disc, and the connecting pin passes through the center positions of connecting block 1, connecting block 2 and the connecting seat at the same time. A reset spring is sleeved on the outer side of the top of the connecting pin, and the bottom end of the reset spring is fixed to the connecting seat, and the top of the reset spring is in contact with the movable disc.

[0008] As a further optimization scheme of the present invention, a support assembly for supporting and reinforcing is arranged between the two groups of beam assemblies, and the support assembly includes support seats respectively arranged at the two ends of the bottom of the supporting beam and fixed to the supporting column, the cross-section of the support seat close to one end of the supporting column is arranged to be trapezoidal, and a triangular groove is opened on the support seat, an oblique support rod with one top end matching the triangular groove is arranged between two adjacent supporting beams, and a triangular support rod is fixedly arranged at the bottom end of the oblique support rod.

[0009] As a further optimization scheme of the present invention, the two right-angled sides of the triangular support rod are respectively located on one end of the two support beams close to each other, and the triangular support rod, the support beam and the support seat are fixedly connected by bolts, and the top of the oblique support rod located on the lower side is also fixedly connected to the support seat by bolts.

[0012] By means of the above technical solution, the present invention provides a guide rail frame for a construction elevator, which has at least the following beneficial effects compared with the prior art: 1. The present invention forms a three-dimensional bearing frame by arranging four supporting columns and three groups of beam assemblies to form a standard section frame, and improves the strength of the standard section frame by clamping components. There is no need to fix the columns and beams by welding to avoid the existence of welding points, and to prevent corrosion at the welding points at the ends of the beams to reduce the structural strength of the guide rail frame. The stability and safety of the guide rail frame are improved, and it is not easily affected by environmental factors, so it has stronger durability and helps to extend the service life of the guide rail frame.

[0013] 2. The present invention arranges three groups of beam assemblies at equal intervals along the axial direction of the supporting columns. Two adjacent supporting beams of each group of beam assemblies are clamped on the middle supporting column. Each group of beam assemblies and four supporting columns together constitute a three-dimensional load-bearing frame to form a spatial truss structure, which makes the overall structure of the guide rail frame more durable. In addition, since there is no corrosion problem that is prone to occur at the welding position, the maintenance frequency and cost of the guide rail frame are greatly reduced, avoiding the trouble of regular inspection and treatment of corrosion at the welding parts.

[0014] 3. The present invention fixes three groups of beam assemblies at the same time by setting a clamping assembly. When the standard section frame is stacked and installed, the limiting sleeve at the bottom of the upper support column is inserted into the inner side of the top of the lower support column. The limiting sleeve presses the topmost movable disk in the support column downward. The topmost movable disk pushes the other two movable disks downward through the movable vertical rod, and pushes the connecting pin to simultaneously penetrate the center position of the connecting block 1, the connecting block 2 and the connecting seat, so as to further reinforce the three groups of beam assemblies on the standard section frame and improve the stability and safety of the overall guide frame.

[0015] 4. The present invention not only strengthens the vertical support of the upper and lower support beams by setting a support assembly, but also connects two adjacent support beams on the same horizontal plane and fixes them by multiple high-strength bolts. Through the combined clamping method, not only the support strength of the guide rail frame can be improved, but also it can be quickly assembled and disassembled, saving the time and process steps required for welding, shortening the construction period, and improving construction efficiency.

[0016] 5. The present invention fixes two adjacent standard section frames by setting a connecting assembly. When the standard section frames are stacked and installed, the upper standard section frame is stacked on the lower standard section frame, and the limiting sleeves at the bottom of the four supporting columns are respectively inserted into the tops of the four supporting columns. While the connecting vertical pipe provides support for the upper standard section frame, the long bolts penetrate the supporting beam at the bottom of the upper standard section frame, the connecting vertical pipe and the supporting beam at the top of the lower standard section frame, thereby fixing the two stacked standard section frames, thereby enhancing the stability and safety redundancy of the guide frame structure.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] First embodiment At present, most of the columns and beams of the standard section of the guide rail frame are welded. However, after long-term use, oil will adhere to the welding joints, and the internal parts may contain acidic substances or electrolytes, forming an electrochemical corrosion environment in the stress concentration area, accelerating the metal oxidation reaction, and causing certain corrosion in the beam welding, which poses a safety hazard. In order to prevent the corrosion of the beam end welding joints and reduce the structural strength of the guide rail frame, the stability of the guide rail frame is improved. Figure 1 - Figure 2 and Figure 5 - Figure 7 As shown, this embodiment provides an elevator guide frame for construction, which consists of a base and a guide frame body 10. The base is installed on a reinforced concrete base by pre-embedded anchor bolts. The guide frame body 10 is used to support the elevator cage and provide a precise vertical running track for the elevator cage. Through the cooperation of the guide rail and the cage roller, the horizontal deviation of the cage is limited to ensure the stability and safety of the lifting process.

[0021] In order to enhance the durability of the guide rail frame and ensure its service life, the guide rail frame body 10 includes a plurality of axially stacked standard section frames 20. The embedded anchor bolts on the base are fixed to the standard section frames 20 at the bottom by threaded connection. The standard section frame 20 is composed of four supporting columns 22 and three groups of cross beam assemblies 21. The four supporting columns 22 are vertically arranged and arranged in a rectangular array, and three groups of horizontally arranged cross beam assemblies 21 are equidistantly distributed along the axial direction of the supporting columns 22. The four supporting columns 22 are fixedly connected by three groups of cross beam assemblies 21. Each group of cross beam assemblies 21 and the four supporting columns 22 together constitute a three-dimensional load-bearing frame to form a spatial truss structure, which makes the overall structure of the guide rail frame more durable. In addition, since there is no corrosion problem that is prone to occur at welding points, the maintenance frequency and cost of the guide rail frame are reduced.

[0022] At present, the welded guide rail frame needs manual regular inspection and treatment of corrosion at the welding parts, which not only poses a safety hazard to the guide rail frame, but also increases the maintenance cost of the guide rail frame. Each group of beam assemblies 21 includes four support beams 211 whose two ends are respectively in contact with two adjacent support columns 22, and the two ends of the four support beams 211 are connected to form a rectangle, and the two ends of the support beam 211 are respectively integrally formed with a connecting block 1 212 and a connecting block 213, and the connecting blocks 1 212 and the connecting blocks 213 at the two ends of the support beam 211 respectively penetrate the two adjacent support columns 22. The support column 22 extends its inner side, a limiting socket 214 matching the connecting block 213 is provided on the connecting block 1 212, and a connecting seat 215 located on the inner side of the supporting column 22 and fixed thereto is provided at one end of the two supporting beams 211 close to each other, and grooves perpendicular to each other are respectively provided on both sides of the connecting seat 215, the connecting block 1 212 and the connecting block 2 213 at one end of the two supporting beams 211 close to each other are perpendicular to each other and inserted into the two grooves on the connecting seat 215, and the connecting block 213 is inserted into the limiting socket 214 on the connecting block 1 212.

[0023] When assembling the standard section frame 20, first insert one end of the supporting beam 211 having the connecting block 1 212 into the supporting column 22 to ensure that there are three supporting beams 211 on the same side of the four supporting columns 22, then place the four supporting columns 22 at the corresponding four corners, and insert the connecting block 213 at the other end of the supporting beam 211 into the corresponding supporting column 22, so that the connecting block 213 is inserted into the limiting socket 214 on the connecting block 1 212, thereby forming the standard section frame 20 into a whole, and the guide rail frame can be quickly assembled and disassembled, saving the time and process steps required for welding and shortening the construction period.

[0024] Second embodiment In order to enhance the connection stability between the support beam 211 and the support column 22 and increase the service life of the guide rail frame, Figure 3 - Figure 4As shown, on the basis of the first embodiment, in this embodiment, a clamping assembly 23 for simultaneously fixing three groups of cross beam assemblies 21 is provided on the inner sides of the four supporting columns 22 respectively. The specific implementation method is that the clamping assembly 23 includes a movable vertical rod 231 slidably arranged on the inner side of the supporting column 22. As shown in the figure, three movable vertical rods 231 are arranged on the axial connecting seat 215. The movable vertical rods 231 penetrate the upper two connecting seats 215 and are slidably connected thereto. A movable disc 232 fixed to the movable vertical rod 231 is provided on the top of the connecting seat 215, and the movable disc 232 is slidably connected to the inner side of the supporting column 22. A connecting pin 233 is fixed to the bottom of the movable disc 232. The center positions of the connecting block 1 212, the connecting block 213 and the connecting seat 215 are all provided with a connecting pin 233. 3, the connecting pin 233 is inserted into the vertical holes of the connecting block 1 212, the connecting block 213 and the connecting seat 215 at the same time, so as to further fix the supporting column 22 and the supporting beam 211, the top outer side of the connecting pin 233 is sleeved with a return spring 234 whose bottom end is fixed to the connecting seat 215, and the top of the return spring 234 contacts the movable disc 232, when the movable disc 232 moves downward, the return spring 234 is squeezed, and the return spring 234 is elastically deformed and compressed. When the standard section frame 20 is disassembled, after the upper supporting column 22 is removed, the return spring 234 restores the elastic deformation to push the movable disc 232 and the connecting pin 233 at the bottom thereof to move upward, and the bottom of the supporting column 22 is integrally formed with a limiting sleeve 235.

[0025] When two standard section frames 20 are stacked, the limiting sleeve 235 at the bottom of the upper supporting column 22 is inserted into the inner side of the top of the lower supporting column 22, and at the same time, the limiting sleeve 235 contacts the topmost movable disc 232 on the inner side of the supporting column 22, and the limiting sleeve 235 presses the topmost movable disc 232 in the supporting column 22 downward, and the topmost movable disc 232 pushes the other two movable discs 232 downward through the movable vertical rod 231, so that the connecting pin 233 is inserted into the vertical holes of the connecting block 1 212, the connecting block 213 and the connecting seat 215 at the same time, thereby further fixing the supporting beam 211 on the supporting column 22, thereby improving the stability and safety of the overall guide frame.

[0026] Third embodiment In order to improve the support strength of the entire standard section frame 20 and enable it to be quickly assembled and disassembled, as Figure 3 - Figure 5As shown, on the basis of the second embodiment, a support assembly 24 for supporting and reinforcing is provided between the two groups of beam assemblies 21 in this embodiment. The specific implementation method is that the support assembly 24 includes support seats 241 respectively arranged at the two ends of the bottom of the support beam 211 and fixed to the support column 22. The cross-section of the support seat 241 close to the end of the support column 22 is set to a trapezoid, and a triangular groove is opened on the support seat 241. The support seat 241 provides support for the support beam 211 to improve the supporting strength of the support beam 211. An oblique support rod 242 with one end of the top matching the triangular groove is provided between two adjacent support beams 211. The angle between the oblique support rod 242 and the horizontal plane is less than 60°. A triangular support rod 243 is fixedly provided at the bottom end of the oblique support rod 242. Through the combination of the oblique support rod 242 and the triangular support rod 243, a stable support structure is formed, which enhances the stability and anti-overturning ability of the guide rail frame.

[0027] The two right-angled sides of the triangular support rod 243 are respectively located on one end of the two supporting beams 211 close to each other, and the triangular support rod 243, the supporting beam 211 and the supporting seat 241 are fixedly connected by bolts, and the top of the oblique support rod 242 located on the lower side is also fixedly connected to the supporting seat 241 by high-strength bolts, and the right-angle end of the triangular support rod 243 matches the supporting column 22. The triangular support rod 243 and the supporting column 22 form a triangular structure, which effectively disperses the force of the elevator guide frame, prevents the guide frame from tilting or collapsing due to weight or external force during use, and ensures the safe operation of the elevator.

[0028] After the standard section frame 20 is assembled, the top of the corresponding oblique support rod 242 is inserted into the triangular groove, and the triangular support rod 243 at the bottom of the oblique support rod 242 is respectively matched with two adjacent support beams 211, and then high-strength bolts are screwed on to install the eight oblique support rods 242 on the support beams 211 of the lower two layers in turn.

[0029] Fourth embodiment In order to ensure the stable connection between the standard section frames 20, the guide rail frame is ensured to remain stable during use. Figure 2 - Figure 3As shown, on the basis of the third embodiment, in this embodiment, a connecting assembly 25 for fixing two standard section frames 20 is provided between two adjacent standard section frames 20. The specific implementation method is that the connecting assembly 25 includes a connecting vertical pipe 251 fixed at both ends of the supporting beam 211 located at the top, and the top of the connecting vertical pipe 251 is in contact with the support seat 241 at the bottom of the upper supporting beam 211, and the supporting beam 211 at the bottom of the upper standard section frame 20 is fixedly connected with the supporting beam 211 at the top of the lower standard section frame 20 by a long bolt 252, and the connecting vertical pipe 251 is sleeved in the middle of the long bolt 252, and the long bolt 252 passes through the supporting beam 211 at the bottom of the upper standard section frame 20, the connecting vertical pipe 251 and the supporting beam 211 at the top of the lower standard section frame 20, so as to fix the upper and lower standard section frames 20.

[0030] When stacking and installing multiple standard section frames 20, the upper standard section frame 20 is stacked on the lower standard section frame 20, and the limiting sleeves 235 at the bottom of the four supporting columns 22 are respectively inserted into the tops of the four supporting columns 22. The connecting vertical pipes 251 provide support for the upper standard section frame 20 while also providing protection for the middle part of the long bolts 252. The supporting cross beams 211 at the bottom of the upper standard section frame 20 and the supporting cross beams 211 of the lower standard section frame 20 are then fixed together by the long bolts 252, and multiple standard section frames 20 are installed in turn.

[0031] The present invention forms a three-dimensional load-bearing frame through four supporting columns 22 and three groups of beam assemblies 21. Two adjacent supporting beams 211 of each group of beam assemblies 21 are clamped on the middle supporting column 22. Each group of beam assemblies 21 and four supporting columns 22 together form a three-dimensional load-bearing frame to form a spatial truss structure. The standard section frame 20 is further fixed by the clamping assembly 23, and the upper and lower standard section frames 20 are fixed by the connecting assembly 25, so as to avoid corrosion at the welding points at the ends of the beams and reduce the structural strength of the guide rail frame, thereby improving the stability and safety of the guide rail frame and reducing the maintenance frequency and cost of the guide rail frame.

[0032] During the actual use of the guide rail frame, the standard section frame 20 is first assembled, and one end of the support beam 211 with the connecting block 1 212 is inserted into the support column 22 to ensure that there are three support beams 211 on the same side of the four support columns 22, and then the four support columns 22 are placed at the corresponding four corners, and the connecting block 213 at the other end of the support beam 211 is inserted into the corresponding support column 22, so that the connecting block 213 is inserted into the limiting plug hole 214 on the connecting block 1 212, so that the standard section frame 20 first forms a three-dimensional frame, and then the top of the corresponding oblique support rod 242 is inserted into the triangular groove, and the triangular support rod 243 at the bottom of the oblique support rod 242 is respectively matched with two adjacent support beams 211, and then the high-strength bolts are screwed on, and then the eight oblique support rods 242 are installed on the support beams 211 of the lower two layers in turn, and the entire standard section frame 20 is assembled; Then, the standard section frame 20 at the bottom is fixedly installed on the base by high-strength bolts, and then multiple standard section frames 20 are stacked and installed, and the upper standard section frame 20 is stacked on the lower standard section frame 20. The limiting sleeves 235 at the bottom of the four supporting columns 22 are respectively inserted into the tops of the four supporting columns 22. The connecting vertical pipes 251 provide support for the upper standard section frame 20 while also providing protection for the middle part of the long bolts 252. The supporting crossbeam 211 at the bottom of the upper standard section frame 20 and the supporting crossbeam 211 of the lower standard section frame 20 are fixed together by the long bolts 252. Multiple standard section frames 20 are installed in turn, so that the entire guide frame 10 is successfully installed.
