Background Technology

[0002] Currently, in mechanical equipment, tank cable trays are used to protect and organize internal cables, but existing fixing methods still have the following drawbacks:

[0003] 1. Inconvenient installation and disassembly: Traditional fixed structures require precise alignment, which makes maintenance or cable replacement time-consuming and labor-intensive;

[0004] 2. Insufficient stability: The fixed structure is easily affected by equipment vibration, which can cause the cable tray to loosen and threaten the safety of the cable.

[0005] 3. High cost: Some existing solutions use metal fasteners, which result in high material and processing costs.

[0006] Therefore, to fill the gaps in the existing technology, this solution proposes a fixing block for a stainless steel tank chain groove. Utility Model Content

[0007] 1. Technical problem to be solved:

[0008] To address the problems existing in the prior art, the purpose of this utility model is to provide a structure that uses a PP material fixing block with milled waist holes to lock the stainless steel tank chain groove with screws, and fixes the stainless steel tank chain groove to the PP plate. This structure aims to solve the problems of inconvenient installation and disassembly and insufficient stability in the existing tank chain groove fixing methods.

[0009] 2. Technical Solution:

[0010] To solve the above problems, the present invention adopts the following technical solution.

[0011] A fixing block for a stainless steel tank chain groove includes a fixing block made of PP material. The upper end of the fixing block is provided with a tank chain groove, and the upper end of the tank chain groove is provided with a plurality of evenly distributed connecting holes.

[0012] The fixing block includes a top seat, a waist hole is provided on the side end of the top seat, a connecting hole is provided on the upper end of the top seat, and an adjustable base is movably connected to the bottom of the top seat.

[0013] A screw is inserted between the fixing block and the tank chain groove. The screw passes through the inner wall between the connecting hole 2, the connecting hole 1, and the waist hole, and a nut is fitted at the bottom.

[0014] A further improvement is that the bottom side of the top seat and the base is provided with a chamfer, and the angle of the chamfer is 45°.

[0015] A further improvement is made in that: a rectangular through hole is provided at the center end of one side of the top seat, and a cylindrical hole is provided at the center end of the bottom of the top seat. A turntable is provided between the inner walls of the rectangular through hole. A threaded sleeve is fixedly connected to the lower end of the turntable. The threaded sleeve is located between the inner walls of the cylindrical hole and is rotatably connected to it. Two limiting grooves are provided at the bottom of the top seat that are symmetrically distributed about the cylindrical hole. A threaded column is fixedly connected to the center end of the upper side of the base. The threaded column is threadedly connected to the threaded sleeve.

The limiting blocks are located between the inner walls of the limiting grooves, and a spring is fixedly connected between the upper and lower inner walls of the two.

[0016] A further improvement is that the screw is of M4-M8 specification, and the height of the slot is 2-3 times the screw diameter.

[0017] 3. Beneficial effects:

[0018] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0019] (1) Significantly improved ease of installation and disassembly: Through the waist hole design on the PP material fixing block, the screw can be flexibly adjusted within the waist hole range without precise alignment, saving about 30% of installation time; when disassembling, simply loosen the screw to quickly separate the cable tray, greatly simplifying the cable maintenance and replacement process.

[0020] (2) Enhanced structural stability: The double fixing structure of screws and PP board (welded or screwed connection) is adopted. Combined with the high toughness and impact resistance of PP material, it effectively resists the vibration and mechanical stress during equipment operation. Tests show that the cable tray does not loosen under 50Hz frequency and 2mm amplitude vibration, ensuring the long-term safe operation of the cable.

[0036] Please see Figures 1-3 A fixing block for a stainless steel tank chain groove includes a fixing block 1 made of PP material. The upper end of the fixing block 1 is provided with a tank chain groove 2, and the upper end of the tank chain groove 2 is provided with a plurality of evenly distributed connecting holes 3.

[0037] The fixing block 1 includes a top seat 11, a waist hole 12 is provided on the side end of the top seat 11, a connecting hole 13 is provided on the upper end of the top seat 11, and an adjustable base 14 is movably connected to the bottom of the top seat 11.

[0038] A screw 4 is inserted between the fixing block 1 and the tank chain groove 2. The screw 4 passes through the inner wall between the connecting hole 2 3, the connecting hole 1 13, and the waist hole 12, and a nut 5 is fitted at the bottom.

[0039] More specifically: the bottom side of the top seat 11 and the base 14 is provided with a chamfer 15, and the angle of the chamfer 15 is 45°.

[0040] More specifically: a rectangular through hole 111 is provided at the center end of one side of the top seat 11, and a cylindrical hole 112 is provided at the center end of the bottom of the top seat 11. A turntable 113 is provided between the inner walls of the rectangular through hole 111. A threaded sleeve 114 is fixedly connected to the lower end of the turntable 113. The threaded sleeve 114 is located between the inner walls of the cylindrical hole 112 and is rotatably connected to it. Two limiting grooves 115 are provided at the bottom of the top seat 11, which are symmetrically distributed about the cylindrical hole 112. A threaded column 116 is fixedly connected to the center end of the upper side of the base 14. The threaded column 116 is threadedly connected to the threaded sleeve 114. Two limiting blocks 117 are fixedly connected to the upper end of the base 14, which are symmetrically distributed about the threaded column 116. The limiting blocks 117 are located between the inner walls of the limiting grooves 115, and a spring 118 is fixedly connected between the upper and lower inner walls of the two.

[0041] More specifically: the screw 4 is of size M4-M8, and the height of the waist hole 12 is 2-3 times the screw diameter.

[0042] During the use of this solution, the personnel first arrange multiple fixing blocks 1 along the preset position on the bottom side of the tank chain groove 2, so that the second connecting hole 3 of the fixing block 1 is aligned with the corresponding hole at the bottom of the groove.

[0043] Then, screw 4 is inserted into the second connecting hole 3 and the waist-shaped hole 12 of the fixing block 1 in sequence. Then, screw nut 5 into the bottom of screw 4 and tighten it to achieve a stable connection between fixing block 1 and tank chain groove 2.

[0044] Among them, under the operation of the height adjustment mechanism of fixed block 1,

[0045] Personnel can rotate the turntable 113 to drive the threaded sleeve 114, which is fixed coaxially with it, to rotate synchronously. Since the limiting block 117 is embedded in the limiting groove 115, the rotational movement of the threaded sleeve 114 is constrained to only axial displacement. Finally, under the meshing action of the threaded sleeve 114 and the threaded column 116, the rotation of the turntable 113 is converted into the vertical linear movement of the threaded column 116, thereby dynamically adjusting the distance between the top seat 11 and the base 14 to adapt to different installation planes.

[0046] In this embodiment, the distance between the top seat 11 and the base 14 can be adjusted infinitely within the range of 5-20mm to meet the needs of diverse scenarios; the limiting groove 115 and the thread engagement provide double constraint to ensure that there is no risk of the structure reverting after adjustment.

[0047] Example 2: Installation steps of PP material fixing block 1

[0048] Step 1: Make a PP material fixing block

[0049] A rectangular block 1 is made from PP sheet with a thickness of 5-10mm using a milling machine.

[0050] An oblong hole 12 is milled into the surface of the fixed block (attached). Figure 2 The waist hole is 12mm long and 5mm wide, and is compatible with M6 screws.

[0051] A chamfer of 15° is machined on one side of the bottom of the fixing block (see attached image). Figure 2 The chamfer angle is 45° to avoid interference of the welding rod during welding.

[0052] Step 2: Connect the tank track groove 2

[0053] Place fixing block 1 on the bottom side of stainless steel tank chain groove 2 (attached) Figure 1 Adjust the waist hole 12 to align with the screw hole in the wire groove;

[0054] Use an M6 screw 4 to pass through the waist hole 12 and screw in the nut 5. After initial tightening, adjust the position of the wire groove, and finally tighten it completely. (See attached image) Figure 1 ).

[0055] Step 3: Fix to PP board

[0056] Welding method: Use a plastic welding gun to weld the bottom surface of fixing block 1 to the PP board. The welding temperature is set to 250-300℃ (see attached image). Figure 1 );

[0057] Screw fixing method: Pre-drilled screw holes are made in the PP board, and the fixing block is connected to the PP board with M6 screws.

[0058] Effect verification

[0059] During installation, the 12-hole screw position can be adjusted by ±5mm, saving approximately 30% of alignment time.

[0060] Under vibration testing (frequency 50Hz, amplitude 2mm), the cable tray remained secure;

[0061] PP material has better corrosion resistance than metal and reduces costs by 40%.

[0062] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
