Description

Technical Field

[0001] This utility model belongs to the field of tunnel processing technology, and in particular relates to a tunnel cable trench template walking device. Background Technology

[0002] In tunnel construction, the pouring of cable trenches is a crucial step in ensuring the safe laying of power, communication and other pipelines in the tunnel. Cable trenches are usually formed by cast-in-place concrete, and their construction quality is directly related to the safety and reliability of tunnel operation. In this process, the formwork system plays a vital role, determining the dimensional accuracy, linear smoothness and inner wall finish of the cable trench.

[0003] Traditional formwork systems mostly employ loosely assembled steel or wooden formwork, which is manually assembled, supported, and fixed on-site. This method suffers from several drawbacks: the entire process of moving, assembling, and dismantling the formwork relies on manual labor, resulting in extremely high labor intensity, long construction cycles, and difficulties in adjusting the formwork position, making it hard to ensure the smooth alignment of multiple trench sections. Furthermore, the poor guidance system makes it prone to deviating from the pre-set track or getting stuck against the sidewalls when moving within the tunnel. To address these issues, we have developed a tunnel cable trench formwork walking device to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a tunnel cable trench formwork walking device. By using assembly strips and rollers, it is convenient for the rapid positioning and continuous construction of the formwork, reducing the time and labor intensity of manual formwork handling. At the same time, the use of auxiliary wheels ensures that the auxiliary wheels are always in contact with the inner wall of the track, and the distance between the L-shaped strips and the U-shaped strips can be flexibly adjusted.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a tunnel cable trench template walking device, including a base plate; multiple sets of arrayed rollers are fixed on the lower end face of the base plate, an L-shaped strip is provided above the base plate, and a U-shaped strip is provided at the same height as the L-shaped strip. Two sets of horizontal bars that connect with the inner sidewall of the U-shaped strip are fixed on the end face of the L-shaped strip. Multiple sets of evenly distributed assembly strips are welded between the two sets of horizontal bars. A cylinder is fixed on the upper end face of both sets of horizontal bars. An auxiliary wheel is rotatably connected to the end face of the U-shaped strip opposite to the L-shaped strip.

[0006] The present invention is further configured such that a plurality of positioning cylinders are fixed on the upper end surface of the base plate in a linearly evenly distributed manner, and ground nails are provided inside the positioning cylinders.

[0007] The present invention is further configured such that connecting strips are fixedly connected to the upper end of the base plate at both ends of the lower side of the L-shaped strip, and abutting plates are provided at the positions between the two sets of connecting strips.

[0008] The present invention is further configured such that two sets of symmetrically arranged reinforcing plates are provided on the side of the abutment plate near the roller, and the reinforcing plates are welded to the upper end of the base plate.

[0009] The present invention is further configured such that the piston end of the cylinder is equipped with a linkage plate that is bolted to the upper end face of the U-shaped bar.

[0010] The present invention is further configured such that the two ends of the U-shaped strip are respectively connected to the side of the adjacent horizontal strip, and the side of the U-shaped strip connected to the horizontal strip is provided with a sliding groove.

[0011] The present invention is further configured such that a sliding plate is slidably provided at the end of the groove away from the L-shaped strip, and the sliding plate is fixed at the end face of the horizontal strip.

[0012] This utility model has the following beneficial effects: This utility model provides a stable installation foundation for cable trench formwork through a support frame composed of L-shaped bars, horizontal bars, and assembly bars. The assembly bars are evenly distributed, which facilitates the bolt connection of the formwork and ensures that the formwork does not shift or deform during the pouring process. Rollers are installed at the lower end of the base plate, which allows the entire device to move flexibly on the tunnel surface, facilitating the rapid positioning and continuous construction of the formwork and reducing the time and labor intensity of manual formwork handling.

[0013] This invention utilizes an auxiliary wheel that engages during the template's travel, providing guidance and reducing frictional resistance. This ensures the entire device moves smoothly and is less prone to jamming. The cylinder drives the U-shaped strip to slide along the groove, ensuring the auxiliary wheel remains in contact with the inner wall of the track at all times. The distance between the L-shaped strip and the U-shaped strip can be flexibly adjusted. Attached Figure Description

Example

[0020] Please see Figures 1 to 3 This utility model relates to a tunnel cable trench formwork walking device, comprising a base plate 1. The base plate 1 serves as the basic support platform for the device, connecting rollers 102, positioning cylinders 103, and other structures, supporting the entire device and formwork system. Multiple sets of arrayed rollers 102 are fixed to the lower end face of the base plate 1, installed below the base plate 1, allowing the entire device to move flexibly on the tunnel surface, facilitating the positioning and movement of the formwork. An L-shaped strip 2 is provided above the base plate 1, serving as the basic structure for formwork installation. It is connected to U-shaped strips 4 via horizontal strips 201 to form a stable formwork support frame. A section at the same height as the L-shaped strip 2 is... The U-shaped strip 4 and L-shaped strip 2 are provided with two sets of horizontal bars 201 fixed to the end face of the U-shaped strip 4 and connected to the inner side wall of the U-shaped strip 4. Multiple sets of evenly distributed assembly bars 202 are welded between the two sets of horizontal bars 201. Cylinders 3 are fixed to the upper end face of the two sets of horizontal bars 201. The U-shaped strip 4 and L-shaped strip 2 cooperate to form an adjustable structure. The position of the U-shaped strip 4 is controlled by the cylinders 3, so that the U-shaped strip 4 can be adjusted. The end face of the U-shaped strip 4 opposite to that of the L-shaped strip 2 is rotatably connected to the auxiliary wheel 401. The auxiliary wheel 401 is installed at the end of the U-shaped strip 4 and contacts the tunnel side wall during the movement of the template to reduce friction and guide the direction of movement.

[0021] Furthermore, multiple positioning cylinders 103 are fixed on the upper surface of the base plate 1 in a linear and evenly distributed manner. Each positioning cylinder 103 is equipped with a ground nail 101. The ground nail 101 is inserted into the positioning cylinder 103 and driven into the ground to enhance the stability of the device during the pouring process, realize the temporary fixation of the device in the construction position, and prevent movement. The L-shaped strip 2 has connecting strips 105 fixed at both ends of its lower side, which are fixedly connected to the upper end of the base plate 1. Abutment plates 104 are provided between the two sets of connecting strips 105. Two sets of symmetrically arranged reinforcing plates 106 are provided on the side of the abutment plate 104 near the roller 102. The reinforcing plates 106 are welded to the upper end of the base plate 1. The abutment plates 104 are located between the connecting strips 105 to abut against the side of the template and enhance the stability of the template installation. The reinforcing plates 106 are welded between the base plate 1 and the abutment plates 104 to enhance the support strength of the abutment plates 104 and prevent deformation.

[0022] Specifically, the piston end of the cylinder 3 is equipped with a linkage plate 301 that is bolted to the upper end face of the U-shaped bar 4. Both ends of the U-shaped bar 4 are connected to the side of the adjacent horizontal bar 201. The side of the U-shaped bar 4 connected to the horizontal bar 201 is provided with a sliding groove 402. The end of the sliding groove 402 away from the L-shaped bar 2 is slidably provided with a sliding plate 203, and the sliding plate 203 is fixed at the end face of the horizontal bar 201. The sliding groove 402 is opened on the side of the U-shaped bar 4 and cooperates with the sliding plate 203 on the horizontal bar 201 to realize the sliding adjustment of the U-shaped bar 4 along the direction of the horizontal bar 201. The sliding plate 203 restricts the movement direction of the U-shaped bar 4 to ensure smooth movement.

[0023] The operation process of this embodiment is as follows: push the device to the construction position of the tunnel cable trench, move it to the target area through the roller 102, insert the ground nail 101 into the positioning cylinder 103, drive it into the ground, temporarily fix the device to prevent it from moving during the pouring process, install the cable trench template on the assembly strip 202, and then assemble the template and the assembly strip 202 with bolts. Start cylinder 3, which pushes U-shaped bar 4 along the slide groove via linkage plate 301. Adjust the distance between L-shaped bar 2 and U-shaped bar 4 to accommodate cable trench templates of different widths. At the same time, auxiliary wheel 401 contacts the tunnel sidewall during movement to reduce friction and ensure smooth movement. After pouring a section of cable trench, pull out ground nail 101 and move the device to the next construction position via roller 102. Repeat the above steps to achieve continuous movement of the template. After construction is completed, disassemble the template, retrieve ground nail 101, and move the device out of the tunnel via roller 102 for use in the next stage.
