Description

Technical Field

[0001] The present invention relates to the technical field of elevator guide rails, and particularly to an elevator guide rail frame for construction. Background Art

[0002] The core function of the guide rail 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 by four columns and multiple cross beams. The elevator cage runs up and down along the main chord of the guide rail frame through four groups of guiding 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, some oil is extruded and flows along the surface of the rack, forming oil stains that accumulate at the welded joints of the cross beams of the guide rail frame. Over time, corrosion and rust will occur. The corrosion will expand the original weld porosity, slag inclusion and other defects, resulting in uneven local stiffness, which may cause the overall inclination of the guide rail frame, posing certain potential safety hazards. Moreover, when a single column or cross beam is damaged, the entire standard section needs to be replaced, which will cause certain waste. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides an elevator guide rail frame for construction, which solves the problem that the welded joints of the cross beams of the guide rail frame in the prior art are corroded by the flowing out oil for a long time, affecting its safety.

[0004] To solve the above technical problems, the present invention provides the following technical solutions:

[0005] An elevator guide rail frame for construction, including a guide rail frame body for carrying an elevator cage, and the guide rail frame body includes several standard section frames axially stacked. The standard section frame includes four support columns vertically arranged and arranged in a rectangular array, and three groups of horizontally arranged cross beam assemblies. The three groups of cross beam assemblies are equally spaced along the axis of the support columns, and each group of cross beam assemblies and the four support columns together form a three-dimensional load-bearing frame. Inside the four support columns, there are clamping assemblies for simultaneously fixing the three groups of cross beam assemblies;

[0006] The cross beam assembly includes four support cross beams with both ends respectively contacting two adjacent support columns, and the four support cross beams are connected at both ends to form a rectangle. At both ends of the support cross beam, a connecting block one and a connecting block two are integrally formed respectively. The connecting block one and the connecting block two at both ends of the support cross beam respectively penetrate two adjacent support columns and extend to their inner sides. A limiting jack matching the connecting block two is opened on the connecting block one, and at one end where two support cross beams are close to each other, there is a connecting seat fixed to the inner side of the support column. The connecting block one and the connecting block two at one end where two support cross beams are close to each other are inserted into the connecting seat.

[0007] As a further optimized solution of the present invention, the clamping assembly includes a movable vertical rod slidably arranged inside the support column. The movable vertical rod penetrates through the connecting seats in the upper two groups and is slidably connected thereto. A movable disc fixed to the movable vertical rod is arranged at the top of the connecting seat, and the movable disc is slidably connected inside the support column.

[0008] As a further optimized solution of the present invention, a limit sleeve is integrally formed at the bottom of the support column. When a plurality of standard section frames are stacked, the limit sleeve at the bottom of the upper support column is inserted into the inner side of the top of the lower support column, and at the same time, the limit sleeve is in contact with the movable disc at the topmost part inside the support column.

[0009] As a further optimized solution of the present invention, a connecting pin is fixed to the bottom of the movable disc. The connecting pin penetrates through the centers of the first connecting block, the second connecting block and the connecting seat at the same time. A return spring with the bottom end fixed to the connecting seat is sleeved on the outer side of the top of the connecting pin, and the top of the return spring is in contact with the movable disc.

[0010] As a further optimized solution of the present invention, a support assembly for support and reinforcement is arranged between the two crossbeam assemblies. The support assembly includes support seats respectively arranged at both ends of the bottom of the support crossbeam and fixed to the support column. The cross-section of the support seat near one end of the support column is trapezoidal, and a triangular groove is formed on the support seat. An inclined support rod with one end of the top matching the triangular groove is arranged between two adjacent support crossbeams, and a triangular support rod is fixedly arranged at the bottom end of the inclined support rod.

[0011] As a further optimized solution of the present invention, the two right-angle sides of the triangular support rod are respectively located on the mutually approaching ends of the two support crossbeams, and the triangular support rod, the support crossbeam and the support seat are fixedly connected by bolts. The top of the inclined support rod at the lower side is also fixedly connected to the support seat by bolts.

[0012] As a further optimized solution of the present invention, a connecting assembly for fixing two standard section frames is arranged between two adjacent standard section frames. The connecting assembly includes connecting vertical pipes fixed to both ends of the support crossbeam at the top, and the top of the connecting vertical pipe is in contact with the support seat at the bottom of the upper support crossbeam.

[0013] As a further optimized solution of the present invention, the support crossbeam at the bottom of the upper standard section frame and the support crossbeam at the top of the lower standard section frame are fixedly connected by long bolts, and the connecting vertical pipe is sleeved on the middle part of the long bolts.

[0014] By means of the above technical solutions, the present invention provides a guide rail frame for a construction hoist, compared with the prior art, having at least the following beneficial effects:

[0015] 1. The present invention constructs a three-dimensional load-bearing framework by setting four support columns and three groups of crossbeam assemblies, thereby combining them into a standard section frame. The strength of the standard section frame is enhanced through a clamping assembly. There is no need to fix the columns and crossbeams by welding, thus avoiding the existence of welding points and preventing corrosion at the welded joints at the ends of the crossbeams, which could reduce the structural strength of the guide rail frame. This improves the stability and safety of the guide rail frame, is not easily affected by environmental factors, has stronger durability, and helps to extend the service life of the guide rail frame.

[0016] 2. The present invention sets three groups of crossbeam assemblies at equal intervals along the axial direction of the support columns. Two adjacent support crossbeams of each group of crossbeam assemblies are clamped on the middle support column. The three groups of crossbeam assemblies and the four support columns together form a three-dimensional load-bearing framework, forming a space truss structure, making the overall structure of the guide rail frame more durable. And because there is no corrosion problem easily occurring at the welded joints, the maintenance frequency and cost of the guide rail frame are greatly reduced, avoiding the trouble of regularly inspecting and treating the corrosion of the welded parts.

[0017] 3. The present invention sets a clamping assembly to fix the three groups of crossbeam assemblies simultaneously. When the standard section frames are 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 squeezes the movable disk at the topmost part inside the support column downward. The topmost movable disk respectively pushes the other two movable disks downward through the movable vertical rods, and the pushing connecting pin penetrates through the central positions of the connecting block one, the connecting block two, and the connecting seat at the same time, thereby further strengthening the three groups of crossbeam assemblies on the standard section frame and improving the stability and safety of the overall guide rail frame.

[0018] 4. The present invention sets a support assembly to strengthen the vertical support of the upper and lower support crossbeams and connect two adjacent support crossbeams on the same horizontal plane at the same time. It is fixed by multiple high-strength bolts. Through the combined clamping method, not only can the support strength of the guide rail frame be improved, but also it can be quickly assembled and disassembled, saving the time and technological steps required for welding, shortening the construction period, and improving the construction efficiency.

[0019] 5. The present invention sets a connecting assembly to fix two adjacent standard section frames. When the standard section frames are stacked and installed, the upper standard section frame is stacked on the lower standard section frame. The limiting sleeves at the bottoms of the four support columns are respectively inserted into the tops of the four support columns. While the connecting vertical pipe provides support for the upper standard section frame, the long bolts penetrate through the support crossbeam at the bottom of the upper standard section frame, the connecting vertical pipe, and the support crossbeam at the top of the lower standard section frame, thereby fixing the two stacked standard section frames up and down and enhancing the stability and safety redundancy of the guide rail frame structure.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] The first embodiment

[0036] Most of the columns and crossbeams of the current standard sections of the guide rail frame are welded. After long-term use, there will be oil stains attached to the welded joints, which may contain acidic substances or electrolytes inside, forming an electrochemical corrosion environment in the stress concentration area, accelerating the metal oxidation reaction, resulting in a certain degree of corrosion in the crossbeam welding, and there are potential safety hazards. In order to prevent the corrosion of the welded joints at the ends of the crossbeams and reduce the structural strength of the guide rail frame, the stability of the guide rail frame is improved. As Figure 1 - Figure 2 and Figure 5 - Figure 7 shown, this embodiment provides a guide rail frame for a construction hoist, which is composed of a base and a guide rail frame body 10. The base is installed on a reinforced concrete foundation through embedded anchor bolts. The guide rail frame body 10 is used to carry the hoist cage and provide an accurate vertical running track for the hoist cage. Through the cooperation of the guide rail and the cage rollers, the horizontal offset of the cage is restricted, ensuring the smoothness and safety of the lifting process.

[0037] In order to enhance the durability of the guide rail frame and ensure its service life, the guide rail frame body 10 includes a number of standard section frames 20 stacked axially. The embedded anchor bolts on the base are fixed to the standard section frame 20 at the bottom through threaded connections. The standard section frame 20 is composed of four support columns 22 and three groups of crossbeam assemblies 21. The four support columns 22 are vertically arranged and arranged in a rectangular array, and the three horizontally arranged crossbeam assemblies 21 are equally spaced along the axial direction of the support columns 22. The four support columns 22 are fixedly connected through the three crossbeam assemblies 21. Each crossbeam assembly 21 and the four support columns 22 together form a three-dimensional load-bearing frame, forming a space truss structure, making the overall structure of the guide rail frame more durable, and due to the absence of corrosion problems that are prone to occur at the welded joints, reducing the maintenance frequency and cost of the guide rail frame.

[0038] At present, the guide rail frames connected by welding require manual regular inspection and treatment of the corrosion at the welding parts. This not only poses a safety hazard to the guide rail frames but also increases the maintenance cost of the guide rail frames. Each set of crossbeam assemblies 21 includes four support crossbeams 211 with both ends respectively contacting two adjacent support columns 22, and the two ends of the four support crossbeams 211 are connected to form a rectangle. At both ends of the support crossbeam 211, a first connecting block 212 and a second connecting block 213 are integrally formed respectively. The first connecting block 212 and the second connecting block 213 at both ends of the support crossbeam 211 respectively penetrate through two adjacent support columns 22 and extend to their inner sides. A limit jack 214 matching the second connecting block 213 is provided on the first connecting block 212. And at one end where two support crossbeams 211 are close to each other, there is a connecting seat 215 located inside the support column 22 and fixed to it. On both sides of the connecting seat 215, grooves perpendicular to each other are respectively opened. The first connecting block 212 and the second connecting block 213 at one end where two support crossbeams 211 are close to each other are perpendicular to each other and inserted into the two grooves on the connecting seat 215, and the second connecting block 213 is inserted into the limit jack 214 on the first connecting block 212.

[0039] When assembling the standard section frame 20, first insert one end of the support crossbeam 211 with the first connecting block 212 on the support column 22 to ensure that there are three support crossbeams 211 on the same side of the four support columns 22. Then place the four support columns 22 at the corresponding four corners, and insert the second connecting block 213 at the other end of the support crossbeam 211 into the corresponding support column 22, so that the second connecting block 213 is inserted into the limit jack 214 on the first connecting block 212. Thus, the standard section frame 20 can be first formed 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.

[0040] Second Embodiment

[0041] In order to strengthen the connection stability between the support crossbeam 211 and the support column 22 and improve the service life of the guide rail frame, as Figure 3 - Figure 4As shown, on the basis of the first embodiment, in this embodiment, a clamping assembly 23 for simultaneously fixing three sets of crossbeam assemblies 21 is provided on the inner sides of the four support columns 22. The specific implementation manner is that the clamping assembly 23 includes a movable vertical rod 231 slidably arranged on the inner side of the support column 22. As shown in the figure, there are three axial connection seats 215. The movable vertical rod 231 passes through the upper two connection seats 215 and is slidably connected thereto. At the top of the connection seat 215, a movable disc 232 fixed to the movable vertical rod 231 is provided, and the movable disc 232 is slidably connected inside the support column 22. A connection pin 233 is fixed to the bottom of the movable disc 232. Vertical holes matching the connection pin 233 are opened at the central positions of the first connection block 212, the second connection block 213, and the connection seat 215. The connection pin 233 is inserted into the vertical holes of the first connection block 212, the second connection block 213, and the connection seat 215 at the same time, so as to further fix the support column 22 and the support crossbeam 211. A return spring 234 with its bottom end fixed to the connection seat 215 is sleeved on the outer side of the top of the connection pin 233, and the top of the return spring 234 is in contact with the movable disc 232. When the movable disc 232 moves downward, the return spring 234 is compressed and elastically deformed. When disassembling the standard section frame 20, after the upper support column 22 is removed, the return spring 234 recovers its elastic deformation and pushes the movable disc 232 and the connection pin 233 at its bottom upward. A limit sleeve 235 is integrally formed at the bottom of the support column 22.

[0042] When two standard section frames 20 are stacked, the limit sleeve 235 at the bottom of the upper support column 22 is inserted into the inner side of the top of the lower support column 22, and at the same time, the limit sleeve 235 is in contact with the movable disc 232 at the topmost part inside the support column 22. By pressing the movable disc 232 at the topmost part inside the support column 22 downward through the limit sleeve 235, the topmost movable disc 232 respectively pushes the other two movable discs 232 downward through the movable vertical rod 231, so that the connection pin 233 is inserted into the vertical holes of the first connection block 212, the second connection block 213, and the connection seat 215 at the same time, thereby further fixing the support crossbeam 211 on the support column 22 and improving the stability and safety of the overall guide rail frame.

[0043] Third Embodiment

[0044] 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 in the figure, on the basis of the second embodiment, a support assembly 24 for support and reinforcement is provided between two groups of crossbeam assemblies 21 in this embodiment. The specific implementation manner is that the support assembly 24 includes support seats 241 respectively arranged at both ends of the bottom of the support crossbeam 211 and fixed to the support columns 22. The cross-section of one end of the support seat 241 close to the support column 22 is trapezoidal, and a triangular groove is provided on the support seat 241. The support seat 241 provides a supporting effect on the support crossbeam 211 to improve the supporting strength of the support crossbeam 211. An inclined support rod 242 with one end of the top matching the triangular groove is arranged between two adjacent support crossbeams 211. The included angle between the inclined support rod 242 and the horizontal plane is less than 60°. A triangular support rod 243 is fixedly arranged at the bottom end of the inclined support rod 242. Through the combination of the inclined support rod 242 and the triangular support rod 243, a stable support structure is formed, enhancing the stability and anti-overturning ability of the guide rail frame.

[0045] Two right-angled sides of the triangular support rod 243 are respectively located on the mutually close ends of two support crossbeams 211, and the triangular support rod 243, the support crossbeam 211 and the support seat 241 are fixedly connected by bolts. The top of the inclined support rod 242 located on the lower side is also fixedly connected to the support seat 241 by high-strength bolts. The right-angled end of the triangular support rod 243 matches the support column 22. The triangular support rod 243 and the support column 22 form a triangular structure, effectively dispersing the force on the elevator guide rail frame, preventing the guide rail frame from tilting or collapsing due to the action of weight or external force during use, and ensuring the safe operation of the elevator.

[0046] After the standard section frame 20 is assembled, the top of the corresponding inclined support rod 242 is inserted into the triangular groove. The triangular support rods 243 at the bottom of the inclined support rod 242 are respectively matched with two adjacent support crossbeams 211. Then, high-strength bolts are screwed on, and the eight inclined support rods 242 are sequentially installed on the support crossbeams 211 of the lower two layers.

[0047] Fourth Embodiment

[0048] In order to ensure the stable connection between the standard section frames 20 and ensure that the guide rail frame remains stable during use, as Figure 2 - Figure 3As shown in the figure, on the basis of the third embodiment, a connection component 25 for fixing two adjacent standard section frames 20 is provided between the two adjacent standard section frames 20. Specifically, the connection component 25 includes connection vertical pipes 251 fixed at both ends of the support cross beam 211 at the top. The top of the connection vertical pipe 251 is in contact with the support seat 241 at the bottom of the upper support cross beam 211. The support cross beam 211 at the bottom of the upper standard section frame 20 and the support cross beam 211 at the top of the lower standard section frame 20 are fixedly connected by long bolts 252. The connection vertical pipe 251 is sleeved in the middle of the long bolt 252. The long bolt 252 penetrates through the support cross beam 211 at the bottom of the upper standard section frame 20, the connection vertical pipe 251, and the support cross beam 211 at the top of the lower standard section frame 20, thereby fixedly connecting the upper and lower standard section frames 20.

[0049] When stacking and installing multiple standard section frames 20, the upper standard section frame 20 is stacked on the lower standard section frame 20. The limit sleeves 235 at the bottoms of the four support columns 22 are respectively inserted into the tops of the four support columns 22. While the connection vertical pipe 251 provides support for the upper standard section frame 20, it can also provide protection for the middle part of the long bolt 252. Then, the support cross beam 211 at the bottom of the upper standard section frame 20 and the support cross beam 211 of the lower standard section frame 20 are fixed together by the long bolt 252, and multiple standard section frames 20 are installed in sequence.

[0050] In the present invention, a three-dimensional load-bearing framework is formed by four support columns 22 and three groups of cross beam assemblies 21. The two adjacent support cross beams 211 of each group of cross beam assemblies 21 are clamped on the middle support column 22. Each group of cross beam assemblies 21 and the four support columns 22 together form a three-dimensional load-bearing framework, forming a space truss structure. The standard section frame 20 is further fixed by the clamping component 23, and the upper and lower standard section frames 20 are fixed by the connection component 25, avoiding the situation that the corrosion at the welded joints of the cross beam ends reduces the structural strength of the guide rail frame, improving the stability and safety of the guide rail frame, and reducing the maintenance frequency and cost of the guide rail frame.

[0051] During the actual use of the guide rail frame, first, assemble the standard section frame 20. Insert the end of the support cross beam 211 with the first connecting block 212 onto the support column 22, ensuring that three support cross beams 211 are on the same side of the four support columns 22. Then, place the four support columns 22 at the corresponding four corners, and insert the second connecting block 213 at the other end of the support cross beam 211 into the corresponding support column 22, so that the second connecting block 213 is inserted into the limit jack 214 on the first connecting block 212. Thus, the standard section frame 20 first forms a three-dimensional framework. Then, insert the top of the corresponding diagonal support rod 242 into the triangular groove. The triangular support rods 243 at the bottom of the diagonal support rod 242 cooperate with two adjacent support cross beams 211 respectively. Then, screw on the high-strength bolts, and successively install the eight diagonal support rods 242 on the support cross beams 211 of the lower two layers to complete the assembly of the entire standard section frame 20.

[0052] Then, fix and install the standard section frame 20 at the bottom on the base through high-strength bolts. Then, start stacking and installing multiple standard section frames 20. Stack the upper standard section frame 20 on the lower standard section frame 20. The limit sleeves 235 at the bottom of the four support columns 22 are respectively inserted into the tops of the four support columns 22. While the connecting vertical pipe 251 provides support for the upper standard section frame 20, it can also provide protection for the middle part of the long bolt 252. Then, fix the support cross beam 211 at the bottom of the upper standard section frame 20 and the support cross beam 211 of the lower standard section frame 20 together through the long bolt 252, and successively install multiple standard section frames 20 to successfully install the entire guide rail frame body 10.

[0053] It should be noted that in this article, the terms "including", "comprising" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
