Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tools for building cable frames, in particular to an installation and positioning tool for a cable trench support. Background Art

[0002] In the field of power engineering construction, cable racks are used as support points during the laying of cables in cable trenches, and multiple layers of cable racks are designed on the same path to place different types of cables. The installation of cable racks must strictly control the spacing between the upper and lower racks in the same column, and the cable racks on the same layer must maintain consistent horizontality to meet design requirements and ensure that their overall process quality can meet relevant construction specifications and design requirements.

[0003] In order to ensure that the installation of the cable trench bracket meets the requirements, the current installation plan for the cable trench bracket is: when constructing the cable trench, the construction workers will embed the relevant embedded parts in the side wall of the cable trench; before the cable trench bracket is constructed, the construction workers will first mark the horizontal line of each layer of the bracket on the embedded parts. After the horizontal line of each layer is leveled, the verticality of each column of bridges will be checked to ensure that the bridges in the same column are in the same vertical plane. After the horizontal line and the vertical line are "crossed" and marked, one person will be responsible for straightening the bracket to the marked position, while the other person will weld and fix the bracket and the embedded parts. This plan has the following disadvantages:

[0004] ①Before welding, the bracket positioning and marking are required, and each layer needs to be positioned;

[0005] ② The cable trench space is relatively small, and the bracket welding requires one person to weld and another person to coordinate, which makes the construction inconvenient and inefficient. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a cable trench bracket installation and positioning tool which can complete the positioning and welding of each layer of brackets by one person, make the spacing of each layer of brackets consistent, and is simple and convenient to operate.

[0007] In order to solve the above technical problems, the technical solution of the utility model is: a cable trench bracket installation and positioning tool, comprising a relatively arranged reference frame and an adjustment and positioning frame, the reference frame is equipped with a bracket spacing device, the adjustment and positioning frame is equipped with a bracket leveling device, and a level ruler is also fixedly installed on the side wall of the adjustment and positioning frame;

[0008] The distance - setting device of the bracket includes a distance - setting bolt movably arranged through the middle of the top end of the reference frame. A distance - setting upper magnet block is fixed to the bottom end of the distance - setting bolt. A distance - setting lower magnet block, which is arranged opposite to the distance - setting upper magnet block, is fixed to the middle of the bottom end of the reference frame. The distance between the bottom surface of the distance - setting upper magnet block and the bottom surface of the distance - setting lower magnet block is the designed distance between two adjacent cable trench brackets.

[0009] As a preferred technical solution, the leveling device of the bracket includes a leveling bolt movably arranged through the middle of the top end of the adjustment and positioning frame. A leveling upper magnet block is fixed to the bottom end of the leveling bolt. A leveling lower magnet block, which is arranged opposite to the leveling upper magnet block, is fixed to the middle of the bottom end of the adjustment and positioning frame.

[0010] As a preferred technical solution, the distance - setting bolt is inserted through the reference frame. Distance - setting locking nuts, which are used in cooperation, are oppositely arranged on both sides of the reference frame on the distance - setting bolt.

[0011] The leveling bolt is inserted through the adjustment and positioning frame. Leveling locking nuts, which are used in cooperation, are oppositely arranged on both sides of the adjustment and positioning frame on the leveling bolt.

[0012] As a preferred technical solution, mounting and fixing seats are respectively and fixedly connected to the bottom end of the distance - setting bolt, the bottom end of the leveling bolt, the bottom end of the reference frame, and the bottom end of the adjustment and positioning frame.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments. In the following detailed description, only some exemplary embodiments of the present utility model are described by way of illustration. It is understood that those of ordinary skill in the art can recognize that the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of protection of the claims.

[0021] As Figure 1 and Figure 2 shown, the installation and positioning tooling for cable trench brackets is used for the positioning and installation between two adjacent brackets during the construction of cable trench brackets. Specifically, it includes a reference frame 1 and an adjustment and positioning frame 2 arranged oppositely. A bracket spacing device is assembled on the reference frame 1, and a bracket leveling device is assembled on the adjustment and positioning frame 2. A spirit level 3 is also fixedly installed on the side wall of the adjustment and positioning frame 2. The reference frame 1 cooperates with the bracket spacing device to determine the spacing between two adjacent brackets, making it consistent with the design distance to meet the installation requirements. The adjustment and positioning frame 2 is adjusted to the same height as the reference frame 1 through the bracket leveling device, and the horizontal state of the two is determined with the help of the spirit level 3. Finally, with the cooperation of the bracket spacing device and the bracket leveling device, the spacing of the lower-layer brackets is determined to assist in welding and installation.

[0022] Among them, the bracket spacing device includes a spacing bolt 4 movably arranged through the middle of the top end of the reference frame 1. A spacing upper magnet block 5 is fixed to the bottom end of the spacing bolt 4. In this embodiment, the spacing bolt 4 is inserted through the reference frame 1. On both sides of the reference frame 1 on the spacing bolt 4, there are cooperating spacing locking nuts 6. Through the spacing bolt 4, the height of the spacing upper magnet block 5 fixedly installed at its lower end can be adjusted. After adjustment, with the cooperation of the two spacing locking nuts 6, the fixing of the spacing bolt 4 is realized, and finally the height of the spacing upper magnet block 5 is maintained. A spacing lower magnet block 7 opposite to the spacing upper magnet block 5 is fixed to the middle of the bottom end of the reference frame 1. The distance H between the bottom surface of the spacing upper magnet block 5 and the bottom surface of the spacing lower magnet block 7 is the design spacing between two adjacent cable trench brackets. Thus, the purpose of adjusting the height of the spacing upper magnet block 5 by the spacing bolt 4 is to adjust the size of the distance H between the bottom surface of the spacing upper magnet block 5 and the bottom surface of the spacing lower magnet block 7 to make it consistent with the design distance.

[0023] The reference frame 1 and the adjustment and positioning frame 2 are both set as rectangular frames, and at least two connecting cross beams 8 are arranged and connected between the reference frame 1 and the adjustment and positioning frame 2, so that the reference frame 1 and the adjustment and positioning frame 2 form an integral structure, facilitating a one-time transfer of the entire tooling position after the bracket is installed.

[0024] The bracket leveling device includes a leveling bolt 9 movably arranged through the middle of the top end of the adjustment and positioning frame 2. A leveling upper magnet block (whose structure and assembly method with the leveling bolt 9 are the same as those of the distance - setting upper magnet block 5 and the distance - setting bolt 4) is fixed to the bottom end of the leveling bolt 9. A leveling lower magnet block 11 opposite to the leveling upper magnet block is fixed to the middle of the bottom end of the adjustment and positioning frame 2. The leveling bolt 9 is inserted through the adjustment and positioning frame 2. On both sides of the adjustment and positioning frame 2 on the leveling bolt 9, leveling locking nuts 10 are provided for cooperation. The installation method of the leveling bolt 9 is similar to that of the distance - setting bolt 4 and is also set to adjust the height of the leveling upper magnet block.

[0025] The bottom ends of the distance - setting bolt 4, the leveling bolt 9, the bottom end of the reference frame 1, and the bottom end of the adjustment and positioning frame 2 are respectively fixedly connected with installation fixing seats 12. The installation fixing seats 12 are provided with installation fixing grooves with open bottoms. The distance - setting upper magnet block 5, the leveling upper magnet block, the distance - setting lower magnet block 7, and the leveling lower magnet block 11 are respectively fixed in the corresponding installation fixing grooves to achieve the installation and fixation of each magnet block. A hoop can also be set outside the installation fixing seat 12 or a colloid can be added inside the installation fixing seat 12, etc., to improve the fixation of each magnet block after being placed.

[0026] As Figure 3 shown, the usage process of this embodiment is as follows:

[0027] First, position, set out lines, and weld the cable trench brackets on the topmost layer according to the conventional installation operation method, and use this layer of cable brackets as the reference layer for the installation operation of the next bracket.

[0028] Adjust the distance - setting bolt 4 according to the requirements of the design drawing, so that the distance between the bottom surfaces of the distance - setting upper magnet block 5 and the distance - setting lower magnet block 7 is the designed distance between adjacent two cable trench brackets.

[0029] After the position of the distance - setting upper magnet block 5 is adjusted, the reference frame 1 is sleeved on the cable trench bracket that has been fixed and used as the reference layer, and the distance - setting upper magnet block 5 is adsorbed and fixed on the top end of the cable bracket.

[0030] Adjust the leveling bolt 9 so that the leveling upper magnet block is adsorbed and fixed at the top of the cable bracket. At the same time, observe the spirit level 3 to ensure that the entire tooling remains horizontal and vertical.

[0031] Take the cable trench bracket to be installed in the lower layer, adsorb it to the bottom ends of the fixed-distance lower magnet block 7 and the leveling lower magnet block 11, and make its end abut against the embedded part of the cable trench, and perform the welding installation operation, that is, complete the welding and fixing of the cable trench bracket.

[0032] After the installation is completed, push the entire tooling towards the side of the cable trench bracket to separate the cable trench bracket from each magnet block, remove the entire tooling, and then put the reference frame 1 and the adjustment and positioning frame 2 on the cable trench bracket that has just been installed and fixed as the reference reference layer for the installation of the next cable trench bracket.

[0033] Take the cable trench bracket to be installed and directly adsorb and fix it to the bottom ends of the fixed-distance lower magnet block 7 and the leveling lower magnet block 11, and perform the welding installation.

[0034] After the first adjustment in this embodiment, the spacing is already fixed. During the subsequent installation and use of the cable trench brackets, direct positioning installation can be carried out without further adjustment, so that the spacing between adjacent cable trench brackets is consistent, which is labor-saving and improves the construction efficiency.

[0035] The description of the present invention has been given for purposes of illustration and description, and is not intended to be exhaustive or to limit the invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments were chosen and described in order to best explain the principles of the invention and its practical application, and to enable those of ordinary skill in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.
