Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a pipe roof conduit jacking auxiliary device. Background Art

[0002] A pipe roof utilizes steel pipes or steel inserts as longitudinal pre-supports and steel arches as transverse annular supports, creating a support system with high overall longitudinal and transverse rigidity. This system prevents and limits surrounding rock deformation and allows for the early bearing of surrounding rock pressure. Generally, a pipe roof is arranged circumferentially at regular intervals along part or all of an underground engineering section, forming a steel pipe protection system. Pipe roofs are not necessarily used only at cave entrances; they are also commonly used in larger landslides, typically when surrounding rock conditions are poor or the volume of the landslide is so large that it is impossible to pass through with a double-layered small pipe.

[0003] In order to solve the problem of insufficient strength of the pipe roof, the existing technology adopts the method of inserting steel pipes into the interior of the pipe roof. However, there may be a situation where the size of the steel pipe is consistent with the size of the reserved pipe hole, which makes it difficult to insert the steel pipe. Utility Model Content

[0009] Furthermore, the positioning mechanism includes a positioning plate, the middle of the positioning plate is provided with an auxiliary hole for docking with the pipe hole, and both ends of the positioning plate are provided with inner hole sliders that cooperate with the guide rail mechanism.

[0010] Furthermore, the axial cross-section of the auxiliary hole is trapezoidal, and at least two fixing blocks are provided on the side wall of the auxiliary hole, and the driving wheels are mounted on each of the fixing blocks.

[0011] Furthermore, the main body component is evenly distributed with positioning holes along the arc direction corresponding to the number of the tube holes, and the positioning plate is provided with a limiting device for cooperating with the positioning holes.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] 1. The device has positioning holes on the side of the main body.

[0016] 2. The device uses expansion bolts to fix the entire guide rail mechanism to the side of the main component, maintaining stability during operation and allowing for easy disassembly after work without affecting subsequent work. The gaps between the top slide bar and the curved top bar, and between the bottom slide bar and the curved bottom bar, reinforce the entire device while not affecting the sliding of the positioning mechanism. The reserved pipe holes on the surface of the main component can be inserted with steel pipes to enhance overall stability; positioning holes are opened on the side of the main component, and the positions of the positioning holes correspond one-to-one with the positions of the pipe holes, allowing the positioning mechanism to accurately locate each pipe hole.

The role of the trapezoidal auxiliary holes can make it easier and more accurate to insert the steel pipe into the pipe hole, avoiding the difficulty of inserting due to the size of the pipe hole being consistent with the steel pipe. The setting of the driving wheel eliminates the need for manual pushing when inserting the steel pipe, making the work of inserting the steel pipe more convenient. Pull the handle to make the limit rod no longer engaged with the positioning hole. At this time, you can rotate the positioning plate to find the next pipe hole. When the auxiliary hole coincides with the next pipe hole, the limit rod is engaged in the positioning hole under the push of the limit spring, which prevents the troublesome process of manually positioning the pipe hole and inaccurate positioning, and improves the adaptability of the device.

DETAILED DESCRIPTION

[0024] To make the above features and advantages of the present invention more clearly understood, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0025] refer to Figures 1 to 5

[0026] A pipe roof conduit jacking auxiliary device includes a pair of base plates 4, an arc-shaped main component 1 is installed on the upper side of the pair of base plates, and the side surface of the main component is evenly distributed with a number of pipe holes 13 for inserting steel pipes along the arc direction, so that steel pipes can be inserted through the pipe holes to improve the overall stability; a guide rail mechanism 2 is also provided on the side surface of the main component, and the internal sliding connection of the guide rail mechanism can be positioned and has a positioning mechanism 3 for the steel pipe to pass through and cooperate with the pipe hole, so that the steel pipe can be more conveniently inserted into the pipe hole 13 with the assistance of the positioning mechanism.

[0027] In this embodiment, the guide rail mechanism includes a pair of fixed plates 21 movably connected to the side surfaces of both ends of the main component, a top arc-shaped slide rail is provided between the outer ends of the pair of fixed plates, and a bottom arc-shaped slide rail is provided between the inner ends of the pair of fixed plates. The two ends of the positioning mechanism are respectively slidably connected to the top arc-shaped slide rail and the bottom arc-shaped slide rail.

[0028] In this embodiment, expansion bolts 22 are inserted at both ends of the fixing plate, and mounting holes for the expansion bolts are provided on the fixing plate. The fixing plate is movably connected to the side of the main member via the expansion bolts. This allows for stability during operation and easy removal after work without affecting subsequent work.

[0029] In this embodiment, a curved top rod 23 is fixed between the outer ends of a pair of fixed plates, and a top slide rod 24 is fixed below the curved top rod with a gap 27 between it and the curved top rod, thereby forming a top curved slide rail. A curved bottom rod 25 is fixed between the inner ends of the pair of fixed plates, and a bottom slide rod 26 is fixed above it with a gap 28 between it and the curved bottom rod, thereby forming a bottom curved slide rail. The gaps between the curved top rod and the top slide rod, and between the curved bottom rod and the bottom slide rod, reinforce the entire device while not affecting the sliding movement of the positioning mechanism.

[0030] In this embodiment, the positioning mechanism includes a positioning plate 31, with an auxiliary hole 32 disposed in the center thereof for docking with the tube hole. A first inner hole slider 35, which is designed to be mounted on the top slide bar, and a second inner hole slider 36, which is designed to be mounted on the bottom slide bar, are fixed to the two ends of the positioning plate. Specifically, the first and second inner hole sliders are each U-shaped and fixed to the ends of the positioning plate. The first and second inner hole sliders are correspondingly buckled onto the top and bottom slide bars, respectively, so that the auxiliary hole on the positioning plate can correspond to each tube hole during the sliding process.

[0031] In this embodiment, the auxiliary hole has a trapezoidal axial cross-section, and at least two fixing blocks 33 are disposed on the sidewalls of the auxiliary hole, each of which is mounted with a drive wheel 34. The trapezoidal shape of the auxiliary hole allows the steel pipe to be inserted into the hole more conveniently and accurately, avoiding insertion difficulties caused by the hole and the steel pipe being the same size. The provision of the drive wheel eliminates the need for manual pushing during insertion, making the insertion process more convenient.

[0032] In this embodiment, positioning holes 12 corresponding to the number of pipe holes are evenly distributed along the arc direction on the main component, and a limiting device 37 for cooperating with the positioning holes is provided on the positioning plate, so that the positioning mechanism can be accurately positioned at each pipe hole. With the assistance of the positioning mechanism, the steel pipe can be more conveniently inserted into the pipe hole.

[0033] In this embodiment, the tube holes are neatly arranged on the side of the main component with the center of the main component as the axis; the connecting line between the center of the positioning hole and the tube hole is on the connecting line from the center of the main component to the boundary.

[0034] In this embodiment, the limiting device includes a handle 371, connected to a limiting rod 372 that passes through the positioning plate and is inserted into the positioning hole. A limiting plate 374 is fixed to the limiting rod, and a spring 373 is sleeved on the limiting rod, with one end abutting the limiting plate and the other end abutting the positioning plate. The positioning plate is provided with an escape cavity or recess for the spring to be placed and for the limiting plate to move out of position. The other end of the spring abuts against the side wall of the escape cavity or recess.

[0035] When using the limit device, the handle is pulled so that the limit rod is not engaged with the positioning hole. At this time, the positioning plate can be rotated to find the next pipe hole; when the auxiliary hole coincides with the next pipe hole, the limit rod is engaged in the positioning hole under the push of the limit spring, preventing the manual positioning of the pipe hole from being troublesome and inaccurate.

[0036] The working principle of the device: Figure 1-5As shown, the entire guide rail mechanism 2 is fixed to the side of the main component 1 by expansion bolts 22, so that it remains stable during operation and can be easily disassembled after the work is completed without affecting subsequent work. The gap between the top slide 24 and the arc-shaped top rod 23 and the gap between the bottom slide 26 and the arc-shaped bottom rod 25 can strengthen the entire device while not affecting the sliding of the positioning mechanism 3. The pipe holes 13 reserved on the surface of the main component 1 can be used to insert steel pipes to improve the overall stability. Positioning holes 12 are opened on the side of the main component 1. The positions of the positioning holes 12 correspond to the positions of the pipe holes 13 one by one, so that the positioning mechanism 3 can be accurately positioned at each pipe hole 13. With the assistance of the positioning mechanism 3, the steel pipe can be more conveniently inserted into the pipe hole 13. The positioning mechanism 3 can keep the auxiliary holes 32 on its surface corresponding to each pipe hole 13 during the sliding process through the cooperation of the top slide 24 and the bottom slide 26. The trapezoidal auxiliary hole 32 allows the steel pipe to be inserted into the pipe hole 13 more conveniently and accurately, avoiding the difficulty of insertion caused by the pipe hole 13 being the same size as the steel pipe. The setting of the drive wheel 34 eliminates the need for manual pushing when inserting the steel pipe, making the insertion process more convenient. Pulling the handle 371 so that the limit rod 372 is not engaged with the positioning hole 12, the positioning plate 31 can be rotated to find the next pipe hole 13; when the auxiliary hole 32 coincides with the next pipe hole 13, the limit rod 372 is engaged in the positioning hole 12 under the push of the limit spring 373, preventing the cumbersome process of manually positioning the pipe hole 13 and the inaccurate positioning.
