Description

Technical Field

[0001] The utility model relates to the technical field of cable protection, in particular to a HPVC cable protection pipe fixing frame. Background Art

[0002] The HPVC cable protection tube fixing frame is a device used to fix and support the HPVC cable protection tube to ensure that the cable protection tube remains in a fixed position after installation and will not shift or deform due to external forces. This fixing frame is usually made of metal with good corrosion resistance and sufficient strength.

[0003] In the underground laying of power cables, the role of the HPVC cable protection tube is to protect the cable from external mechanical damage and chemical corrosion, ensuring the safe operation of the cable. The role of the fixing frame is to ensure that the protection tube remains stable in complex and changing terrain environments.

[0004] After the existing cable protection tube is installed on the fixing frame, the protection tube is usually connected with a clamp, and then the clamp is fixed to the fixing frame by bolts. Since the number of cables laid each time is large during the cable laying process, the number of protection tubes used will also increase. Therefore, this installation, connection and fixing method results in that when the protection tube and the fixing frame are installed and fixed, each connection between the protection tube and the fixing frame needs to be fixed by bolts, which results in an extremely wasteful installation process. In addition, in the subsequent maintenance of the protection tube, a large number of bolts also need to be removed, which greatly reduces the installation efficiency.

[0005] Therefore, it is necessary to invent a HPVC cable protection tube fixing frame to solve the above problems. Utility Model Content

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model provides Figure 1-5 The HPVC cable protection tube fixing frame shown includes two columns 1. The columns 1 serve as the main support structure of the fixing frame, providing stable vertical support to ensure the stability of the entire fixing frame. The inner open structure of the column 1 is convenient for matching with the connecting block 21 of the cross frame 2, thereby simplifying the installation and disassembly process. A plurality of cross frames 2 are arranged between the two columns 1. The cross frames 2 are used to connect the two columns 1 to form the overall frame of the fixing frame. The plurality of cross frames 2 are evenly distributed from bottom to top with equal spacing. A baffle 7 is arranged on the front of each cross frame 2. The baffle 7 arranged on the cross frame 2 can prevent the displacement of the clamp 4. A fixing mechanism 3 is arranged above each cross frame 2. The fixing mechanism 3 formed by the combination of the clamp 4 and the pressure plate 5 is used to fix the cable protection tube.

[0029] The fixing mechanism 3 comprises:

[0030] A plurality of clamping rings 4 are arranged above the cross frame 2, and the clamping rings 4 are evenly distributed at equal intervals, and the clamping rings 4 are used to support and adapt the bottom of the cable protection tube;

[0031] The pressure plate 5 is arranged above several clamping rings 4 of the cross frame 2. Several arc-shaped notches 51 are provided at the bottom of the pressure plate 5 and at the corresponding positions of each clamping ring 4. Both ends of the pressure plate 5 are fixedly installed with protrusions 52. Both protrusions 52 are vertically provided with through holes. The pressure plate 5 is used to press and adapt the top of the cable protection tube.

[0032] Furthermore, in the above technical solution, two columns 1 stand opposite to each other, and the inner sides of the two columns 1 are open structures. Connecting blocks 21 are fixedly installed at both ends of the cross frame 2, and the connecting blocks 21 are adapted to the openings on the inner sides of the columns 1, so that the ends of the cross frame 2 can be snapped into the inner openings of the columns 1, which facilitates subsequent fixed installation and connection.

[0033] Furthermore, in the above technical solution, bolts 11 are installed through both sides of the column 1, and the connecting block 21 at the end of the cross frame 2 is fixed to the opening of the column 1 by the bolts 11. A nut 12 is installed at the front end of the bolt 11. A support member 13 is fixedly installed on the inner side of the column 1 and below the end of each cross frame 2. The end of the cross frame 2 is supported by the support member 13 to improve the supporting effect of the cross frame 2 and prevent too many cable protection tubes from being placed on the cross frame 2 to affect the stability of the cross frame 2.

[0034] Furthermore, in the above technical solution, a plurality of equally spaced positioning blocks 22 are fixedly installed on the upper end of the cross frame 2, the number of the positioning blocks 22 is equal to the number of the retaining rings 4, and the bottom grooves 41 of the retaining rings 4 are adapted to the positioning blocks 22 at corresponding positions on the cross frame 2, and are slidably connected.

[0035] Furthermore, in the above technical solution, through holes 23 are vertically opened at both ends of the cross frame 2 and away from the connecting block 21, and positioning rods 6 are vertically arranged on the inner sides of the two columns 1. The positioning rods 6 are used to limit the installation position of the pressure plate 5 above the cross frame 2 to prevent the pressure plate 5 from being unable to be effectively pressed on the clamping ring 4. The two positioning rods 6 respectively penetrate the through holes 23 at both ends of the cross frame 2.

[0036] Furthermore, in the above technical solution, pressing pieces 71 are fixedly installed at both ends of the baffle 7 and at corresponding positions of the through holes 23 at both ends of the cross frame 2. The pressing piece 71 is a vertical L-shaped structure. Notches are provided on the same side of the two pressing pieces 71 and on the same side of the ends of the pressing plate 5. The ends of the pressing plate 5 are pressed by the pressing pieces 71 to prevent the pressing plate 5 from falling off the clamping ring 4, thereby affecting the installation and fixing effect of the cable protection tube on the clamping ring 4.

[0037] Furthermore, in the above technical solution, the two end portions of the baffle plate 7 are connected to the bolts 11 on the front sides of the two columns 1, and the two end portions of the baffle plate 7 are pressed onto the back sides of the nuts 12, and the notches at the ends of the pressing pieces 71 and the pressing plates 5 are matched with the positioning rods 6 and are snap-fitted together.

[0038] The working process of the HPVC cable protection tube fixing frame provided by the utility model when in use is as follows:

[0039] According to the number and size of the cable protection tubes to be laid, a tunnel of corresponding size is dug on the ground, and then the columns 1 are installed on both sides of the tunnel respectively, and the positioning rods 6 are vertically fixed on the inner sides of the two columns 1. Then, a cross frame 2 of appropriate length is selected, and multiple cross frames 2 are installed from bottom to top between the two columns 1, and the connecting blocks 21 at the ends of the cross frames 2 are fixed in the two columns 1 by bolts 11. At the same time, the through holes 23 at both ends of the cross frames 2 pass through the positioning rods 6, and then several clamping rings 4 are installed on each cross frame 2. When installing the clamping ring 4, the clamping groove 41 at the bottom of the clamping ring 4 is slidably engaged with the positioning block 22 on the cross frame 2. Since a protrusion is set at the tail end of the positioning block 22, when the back side of the clamping ring 4 contacts the protrusion at the tail end of the positioning block 22, the installation of the clamping ring 4 on the cross frame 2 is completed. Repeat the above process to complete the installation of all the clamping rings 4.

[0040] After that, all the cable protection tubes are laid on the clamping rings 4 corresponding to the cross frame 2. After the cable protection tubes are laid, multiple pressure plates 5 are covered on all the cable protection tubes in the same row. Then, the pressure plate 5 is pushed to the top of the clamping ring 4, and the notches at both ends of the pressure plate 5 are engaged with the positioning rod 6. Finally, a baffle 7 is installed on the front of each cross frame 2. When installing the baffle 7, the two ends of the baffle 7 are connected to the bolts 11 on the front of the two columns 1, and the nuts 12 are installed. At the same time, the pressing pieces 71 at both ends of the baffle 7 are covered on the two ends of the pressure plate 5, and the notches of the pressing pieces 71 are engaged with the positioning rod 6, so that the installation and fixation of all the cable protection tubes are quickly completed, and the fixing frame of this structure is also more convenient during subsequent disassembly and maintenance.

[0041] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
