Description

Technical Field

[0001] This invention belongs to the field of pipe gallery construction technology, specifically relating to a clamp-type pipe jacking device and method for pipe galleries. Background Technology

[0002] A pipe gallery is a corridor for pipelines. In chemical and related factories, many pipelines are concentrated together and arranged along the outside of the equipment or factory buildings. They are usually in the air and supported by brackets to form a corridor-like shape; a few pipe galleries are located underground.

[0003] The inventors discovered that in current petrochemical plants, the layout of pipe racks is becoming increasingly compact, and the height of pipe racks is also trending downwards. After the process pipelines are installed, supports need to be installed. The supports are usually made of I-beams. In the past, chain hoists were used to assist in hanging the pipes on the upper structural beams. The pipes were then lifted by pulling the chain hoist to install the supports. This method cannot be applied to areas without upper crossbeams or to pipe racks with low heights.

[0004] Therefore, how to carry out pipe jacking operations in areas without upper beams and in pipe corridors with low floor heights is a technical challenge that needs to be solved. Summary of the Invention

[0005] In order to solve the above problems, according to some embodiments, the present invention adopts the following technical solution:

[0006] In a first aspect, the present invention provides a clamp-type pipe jacking device for pipe gallery, comprising: an installation frame and a pipe jacking mechanism, wherein a buckle is provided on one side of the installation frame for fixing the installation frame on a steel beam, and the other side of the installation frame is connected to the pipe jacking mechanism, which is used to perform jacking operations on the steel pipe above the steel beam.

[0007] Furthermore, the buckle includes a hooked screw, one end of which is connected to the mounting frame, and the other end of which is provided with a hook-shaped component that is snapped onto the flange of the steel beam.

[0008] Furthermore, the mounting frame includes a frame body, an upper back baffle, and a lower back baffle. A vertical groove is provided on one side of the frame body, and the upper back baffle and the lower back baffle are installed in the vertical groove. The upper back baffle and the lower back baffle can slide along the vertical groove. An adjusting bolt is also provided in the vertical groove, which is used to fix the position of the upper back baffle and the lower back baffle.

[0009] Furthermore, the upper back panel is located at a predetermined distance above the lower back panel.

[0010] Furthermore, an adjustment block is installed on the upper back baffle, and the adjustment block has a screw mounting hole for installing a hooked screw.

[0011] Furthermore, the adjusting block is connected to the hooked lead screw via an adjusting nut.

[0012] Furthermore, a horizontal groove is provided on one side of the upper back baffle, and an adjusting block is installed in the horizontal groove.

[0013] Furthermore, the lower back baffle has blocks on both sides, which are used to support the edge plates of the I-beam steel beam.

[0014] Furthermore, the pipe jacking mechanism employs a jack.

[0015] Secondly, the present invention provides a method for operating the pipe jacking device for pipe corridors as described in the first aspect, comprising the following steps:

[0016] The mounting frame is fixed to the side of the steel beam using clips;

[0017] The steel pipes above the steel beams are lifted using a jacking mechanism installed on the side of the mounting frame.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. In this invention, a buckle is used to fix the mounting frame on the steel beam. The other side of the mounting frame is connected to the pipe jacking mechanism. The pipe jacking mechanism is used to lift the steel pipe above the steel beam. The pipe jacking mechanism uses hydraulic jacks to lift the pipe. Compared with the traditional chain hoist, the device in this invention is more suitable for parts without upper beams and pipe corridors with low floor height.

[0020] 2. In this invention, both the upper and lower back baffles are equipped with adjustment blocks to accommodate steel beams of different specifications. The hooked screw is equipped with an adjustment nut on the adjustment block to adjust the screw length to accommodate steel beams of different widths. The lower back baffle is equipped with a back block to fit tightly with the lower flange plate of the steel beam, ensuring the stability of the jacking device under force and safe operation.

[0021] Advantages of additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0030] Example 1:

[0031] like Figure 1 As shown in the figure, this embodiment of a clamp-type pipe jacking device for pipe gallery includes an installation frame and a jacking mechanism. One side of the installation frame is provided with a buckle for fixing the installation frame to the steel beam. The other side of the installation frame is connected to the jacking mechanism, which is used to lift the steel pipe above the steel beam.

[0032] The buckle includes an upper back baffle, a lower back baffle, and a hooked screw. The hooked screw is installed on the upper back baffle, and one end of the hooked screw is provided with a hook-shaped component, which is snapped onto the flange of the steel beam. The steel beam is an I-beam.

[0033] In one implementation, the pipe jacking mechanism is a jack.

[0034] In one embodiment, the mounting frame includes a frame body with a vertical groove on one side. An upper back baffle and a lower back baffle are installed in the vertical groove and can slide along the vertical groove. An adjusting bolt is also provided in the vertical groove to fix the position of the upper back baffle and the lower back baffle. The upper back baffle is located at a set distance above the lower back baffle. By adjusting the bolt, the upper back baffle and the lower back baffle can move up and down along the vertical groove to accommodate steel beams of different specifications.

[0035] On the other side of the frame, there is a jack base, on which jacks are installed. The jacks are used to lift the pipe to a set height. Multiple jacks can be installed, or multiple pipe rack pipe jacking devices can be installed at intervals to support and lift the pipe together.

[0036] The upper back baffle has a horizontal groove on one side. An adjusting block is installed in the horizontal groove. The adjusting block can slide along the horizontal groove or be fixed by adjusting bolts. The adjusting block can move left and right along the horizontal groove by adjusting bolts, thereby driving the screw to move horizontally to accommodate pipes of different diameters.

[0037] The adjusting block has a screw mounting hole, and a hooked screw is installed in the mounting hole. One end of the hooked screw has a hook-shaped part, which is used to snap onto one end of the I-beam and is fixedly installed on the top surface of the I-beam.

[0038] The lower back baffle has blocks on both sides, which are used to support the edge plates of the I-beam steel beam and play a fixing role to prevent loss of stability during the lifting process.

[0039] The adjusting stop and the hooked lead screw are connected by an adjusting nut. The length of the hooked lead screw is adjustable, thus adapting to steel beams of different widths. Specifically, the hooked lead screw has a threadless surface for fixed installation. The threaded area of ​​the lead screw can be adjusted by rotating it to change its extension length. The length of the extended section of the lead screw can also be adjusted by rotating the adjusting stop to match the length of the top surface of the I-beam.

[0040] The hook-shaped part with hook screw is fixedly installed at the top plane of the I-beam. The hook screw is fixed and snapped on one side of the top plane of the I-beam, thereby effectively providing support to the mounting frame on the other side, so that the lifting mechanism of the mounting frame can effectively lift the steel pipe.

[0041] In one implementation, two hooked screws are provided, with a certain distance between them. When the jack lifts the steel pipe, the two hooked screws with a set distance effectively support the lifted steel pipe, allowing the lifted steel pipe to be repaired or replaced.

[0042] In one implementation, the jack base is designed to be movable and is also fixed using vertical grooves and adjusting bolts to accommodate jacks of different sizes for lifting.

[0043] In one embodiment, the frame is a vertical channel steel.

[0044] In one implementation, the mounting frame consists of vertical channel steel and upper and lower back baffles. A jack base is welded onto the channel steel to support the jack, and ribs are welded onto the base to strengthen its strength.

[0045] Example 2

[0046] A method for operating a clamp-on pipe rack jacking device includes the following steps:

[0047] The mounting frame is fixed to the side of the steel beam using clips;

[0048] The steel pipes above the steel beams are lifted using a jacking mechanism installed on the side of the mounting frame.

[0049] Specifically, the location for pipe jacking is selected, and the pipe jacking equipment is prepared at the same time;

[0050] The pipe jacking device is manually lifted to be level with the steel beam, and then the hooked screw is hung on the flange plate of the steel beam to suspend it.

[0051] The height of the lower back panel is adjusted by the vertical holes, so that the back panel can lock the lower flange of the steel beam.

[0052] Tighten the adjusting nut to stabilize it;

[0053] After ensuring the pipe jacking device is stable, place the jack on the jack base.

[0054] If the entire pipeline needs to be raised, several additional pipe jacking devices can be installed at adjacent steel beams, and the pipeline can be raised by hand-operated jacks.

[0055] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
