Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline suspension frames, in particular to a pipeline suspension frame for subway tunnel construction. Background Art

[0002] During subway construction, since most of the time the construction is done underground, in order not to affect the movement of vehicles and workers in the tunnel during the construction process, it is often necessary to suspend pipes and cables in the tunnel through suspension frames. Then, after the construction is completed, the pipes and cables are removed from the suspension frames.

[0003] However, in the prior art, when installing the suspension frame, screws are mostly used to install it on the inner top wall of the tunnel. In order to ensure the load-bearing effect of the suspension frame, a plurality of screws are usually installed on one suspension frame. Therefore, it is troublesome during installation and later removal. Moreover, the existing suspension frames are mostly closed frame structures. When removing the pipes and cables later, it is inconvenient to directly remove the pipes and cables from the suspension frame. Summary of the invention

[0004] The utility model aims to solve the problems existing in the prior art and provides a pipeline suspension frame for subway tunnel construction, which can be quickly installed and removed, quickly set up wires and pipes, and quickly retract wires and pipes.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a pipeline suspension frame for subway tunnel construction, including a base plate, a placement frame is provided on the base plate, a hanger penetrating the base plate is provided at the center of the base plate, pipe grooves and wire grooves are symmetrically opened on the top of the placement frame and on both sides of the hanger, the inner walls of the pipe grooves and the wire grooves are both installed with shock-absorbing linings, a connecting plate is provided on the top of the hanger, and expansion nails are provided on the connecting plate, the expansion nails include a nail rod arranged on the connecting plate, a nail head arranged on the nail rod, and an expansion sleeve mounted on the surface of the nail rod, and a mounting plate is provided on the surface of the expansion sleeve.

[0006] Through the above technical solution, during the construction of the subway tunnel, the expansion sleeve is inserted into the pre-drilled installation hole, and then the hanger is pulled downward to retract the nail head, and then the expansion sleeve is stretched open, so as to realize the installation of the entire equipment. After the pipe is installed on the placement rack, the greater the gravity on the hanger, the more the expansion sleeve will be stretched open, and the tighter the connection between the expansion sleeve and the installation hole will be, so that the installation effect will be more stable. When dismantling, the connection plate can be pushed upward to retract the expansion sleeve to the initial diameter, that is, the installation plate can be pulled down to realize dismantling. Compared with the existing hanger that needs to drive multiple screws into the tunnel wall one by one, it is more convenient for both installation and later dismantling.

[0007] When handling pipes and cables used in tunnel construction, after the equipment is installed, pipes or cables can be directly placed on the placement rack from both sides, making pipe laying and cable laying easier. Moreover, without disconnecting the pipes or removing the suspension racks, pipes and cables can be directly removed from the sides of the suspension racks, making pipe removal and cable laying easier, effectively speeding up the construction speed, shortening the project cycle, and thus reducing the construction cost of the entire tunnel project.

[0008] At the same time, pipe troughs and cable troughs are used to hold pipes and cables in place, eliminating the need for additional position limits on pipes and cables, making construction simpler. At the same time, through shock-absorbing linings and the high elasticity of sponge, pipe troughs or cable troughs can better wrap pipes or cables, making them more stable while also having a certain buffering effect.

[0009] Optionally, the inner diameter of the lower end of the wire trough is greater than the inner diameter of the upper end of the wire trough.

[0010] This allows for a better gathering of the cables, more cables to be placed in the duct, and prevents cables from jumping out of the duct.

[0011] Optionally, a triangular support frame fixedly connected to the suspension rod is provided at the bottom of the base plate and on both sides of the suspension rod.

[0012] A triangular support frame is used to provide a more stable support force to the base plate.

[0013] Optionally, an inner hole vertically penetrating the mounting plate is provided on the surface of the mounting plate and located on the inner side of the expansion sleeve, and the nail rod movably passes through the inner hole.

[0014] Optionally, a plurality of expansion nails are arranged side by side and equidistantly.

[0015] Multiple expansion nails can make the hanger more load-bearing.

[0016] Optionally, the length of the nail rod is greater than the length of the expansion sleeve, the nail rod passes through the expansion sleeve, and a flaring groove is provided at the top end of the inner wall of the expansion sleeve.

[0017] Optionally, the diameter of the nail head is the same as the outer diameter of the expansion sleeve, and the vertical cross-section of the nail head is an isosceles trapezoid.

[0018] In the initial state, the nail head is located outside the expansion sleeve, and the expansion sleeve is in the initial diameter state and can be directly inserted into the mounting hole. As the nail rod moves downward, the nail head will gradually embed into the expansion sleeve, thereby causing the expansion sleeve to expand. The more the nail rod moves downward, the more the expansion sleeve expands, and the tighter the connection between the expansion sleeve and the mounting hole will be.

[0019] Compared with the prior art, the beneficial effects of the utility model are as follows: 1. During the construction of a subway tunnel, the expansion sleeve is inserted into the pre-drilled installation hole, and then the hanger is pulled downward to retract the nail head, and then the expansion sleeve is stretched open, thereby realizing the installation of the entire equipment. Moreover, as the pipe is installed on the placement rack, the greater the gravity on the hanger, the wider the expansion sleeve will be stretched, and the tighter the connection between the expansion sleeve and the installation hole will be, thereby making the installation effect more stable. During dismantling, the connection plate is pushed upward to retract the expansion sleeve to its initial diameter, and then the installation plate is pulled down to realize dismantling. Compared with the existing hanger that needs to drive multiple screws into the tunnel wall one by one, it is more convenient for both installation and later dismantling. 2. When laying pipes and cables, after the equipment is installed, the pipes or cables can be placed directly on the rack from both sides, making pipe laying and cable laying simpler; 3. Without disconnecting the pipes or removing the suspension racks, the pipes and cables can be directly removed from the sides of the suspension racks, making it simpler to remove the pipes and cables, effectively speeding up the construction speed, thereby shortening the project cycle and reducing the construction cost of the entire tunnel project; 4. Pipe troughs and cable troughs are used to clamp the pipes and cables, without the need for additional position limiting of the pipes and cables, making construction simpler; 5. Through the shock-absorbing lining and the high elasticity of the sponge, the pipe troughs or cable troughs can better wrap the pipes or cables, making them more stable, while also having a certain buffering effect.

[0024] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution 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 in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "middle", "upper", "lower", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0026] like Figure 1-3 As shown, the specific scheme of the embodiment is as follows: A pipeline suspension frame for subway tunnel construction includes a bottom plate 1, a placement frame 2 is arranged on the bottom plate 1, a suspension rod 3 penetrating the bottom plate 1 is arranged at the center of the bottom plate 1, a pipe groove 21 and a wire groove 22 are symmetrically opened on the top of the placement frame 2 and on both sides of the suspension rod 3, and the inner walls of the pipe groove 21 and the wire groove 22 are both installed with a shock-absorbing lining. The shock-absorbing lining can be sponge, foam or wood.

[0027] When handling pipes and cables used for construction in the tunnel, after the equipment is installed, the pipes or cables can be directly placed on the placement rack 2 from both sides, which makes pipe laying and cable laying easier. Moreover, without disconnecting the pipes and the suspension rack, the pipes and cables can be directly removed from the side of the suspension rack, which makes pipe removal and cable laying easier, effectively speeding up the construction speed, shortening the project cycle, and reducing labor costs, thereby achieving the purpose of reducing the project cost of the entire tunnel project.

[0028] At the same time, the pipe trough 21 and the wire trough 22 are used to clamp the pipes and cables, without the need for additional limiting of the pipes and cables, making the construction simpler. At the same time, through the shock-absorbing lining and the high elasticity of the sponge, the pipe trough 21 or the wire trough 22 can better wrap the pipes or cables, making them more stable and having a certain buffering effect.

[0029] like Figure 1 As shown, in this embodiment, a connecting plate 5 is provided at the top of the suspension rod 3, and an expansion nail 6 is provided on the connecting plate 5. The expansion nail 6 includes a nail rod 61 arranged on the connecting plate 5, a nail head 62 arranged on the nail rod 61, and an expansion sleeve 63 sleeved on the surface of the nail rod 61, and a mounting plate 7 is provided on the surface of the expansion sleeve 63.

[0030] Among them, an inner hole that vertically penetrates the mounting plate 7 is opened on the surface of the mounting plate 7 and located on the inner side of the expansion sleeve 63, and the nail rod 61 moves through the inner hole. A plurality of expansion nails 6 are arranged side by side and at equal distances. A plurality of expansion nails 6 can make the suspension rod 3 more load-bearing.

[0031] Secondly, the diameter of the nail head 62 is the same as the outer diameter of the expansion sleeve 63, and the vertical cross-section of the nail head 62 is an isosceles trapezoid.

[0032] In the initial state, the nail head 62 is located outside the expansion sleeve 63, and the expansion sleeve 63 is in the initial diameter state and can be directly inserted into the mounting hole. As the nail rod 61 moves downward, the nail head 62 will gradually embed into the expansion sleeve 63, thereby allowing the expansion sleeve 63 to expand. The more the nail rod 61 moves downward, the more the expansion sleeve 63 expands, and the tighter the connection between the expansion sleeve 63 and the mounting hole is.

[0033] It should be noted that the length of the nail rod 61 is greater than the length of the expansion sleeve 63. The nail rod 61 passes through the expansion sleeve 63, and a flared groove is provided at the top of the inner wall of the expansion sleeve 63. The design of the flared groove makes it easier for the nail head 62 to expand the expansion sleeve 63.

[0034] Furthermore, when drilling the installation hole, the depth of the installation hole should be greater than the length of the entire expansion nail 6 to ensure that the nail rod 61, the nail head 62, and the expansion sleeve 63 can be fully inserted into the installation hole.

[0035] During subway tunnel construction, the expansion sleeve 63 is inserted into the pre-drilled installation hole, and then the hanger 3 is pulled downward to retract the nail head 62, and then the expansion sleeve 63 is stretched open, thereby realizing the installation of the entire equipment. After the placement rack 2 installs the pipeline, the greater the gravity on the hanger 3, the wider the expansion sleeve 63 will be stretched, and the tighter the connection between the expansion sleeve 63 and the installation hole will be, making the installation effect more stable. When dismantling, the connecting plate 5 is pushed upward to retract the expansion sleeve 63 to the initial diameter, and then the installation plate 7 is pulled down to realize dismantling. Compared with the existing hanger that needs to drive multiple screws into the tunnel wall one by one, it is more convenient for both installation and later disassembly.

[0036] like Figure 1-2 As shown, the inner diameter of the lower end of the wire trough 22 is larger than the inner diameter of the upper end of the wire trough 22 . Such a design can achieve a better gathering effect on the cables, and more cables can be placed in the wire trough 22 , and the cables can be prevented from jumping out of the wire trough 22 .

[0037] In this embodiment, a triangular support frame 4 fixedly connected to the suspension rod 3 is provided at the bottom of the base plate 1 and on both sides of the suspension rod 3. The triangular support frame 4 provides a more stable supporting force to the base plate 1.

[0038] Working principle: When installing the suspension rack, hold the mounting plate 7 and insert the expansion sleeve 63 into the pre-punched mounting hole, then pull the suspension rod 3 downward to retract the nail head 62, and then expand the expansion sleeve 63 to achieve the installation of the entire equipment. After the placement rack 2 is installed with pipes, the greater the gravity on the suspension rod 3, the more the expansion sleeve 63 will be expanded, and the tighter the connection between the expansion sleeve 63 and the mounting hole will be;

[0039] When removing the suspension frame, the connecting plate 5 is pushed upwards, and the nail head 62 extends out of the expansion sleeve 63, so that the expansion sleeve 63 can be retracted to the initial diameter, that is, the installation plate 7 is then pulled down to achieve removal;

[0040] When laying pipes and cables, pipes or cables are placed directly on the placement rack 2 from both sides, with pipes placed in pipe grooves 21 and cables placed in cable grooves 22;

[0041] Without disconnecting the pipes or removing the suspension brackets, the pipes and cables can be directly removed from the sides of the suspension brackets, making it easier to remove the pipes and cables.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
