Description

Technical Field

[0001] This utility model relates to the field of tunnel grouting heating technology, specifically a heating device used in the tunnel grouting process. Background Technology

[0002] Tunnel grouting is a widely used technology in tunnel engineering. It involves drilling holes in the surrounding rock and injecting a specific grout to achieve the purpose of ground reinforcement and waterproofing. When using it, it needs to be heated.

[0003] For example, Chinese patent CN221255178U (A Highway Grouting Device) includes a platform with two pushers fixedly connected to one side. An electrical box is snapped into the edge of the platform, and a barrel is snapped into the middle of the platform. A heating component is fixedly connected inside the barrel. This highway grouting device, through the heating component, operates by activating a battery to power a heating element. The heating element heats the barrel according to a temperature set by a temperature controller, thereby heating the grouting material inside the barrel. In cold winters, highway grouting can affect the fluidity and setting time of the material. Heating increases the material's temperature, allowing it to maintain suitable fluidity even at low temperatures, improving construction efficiency. Heating also makes the binder in the material easier to dissolve and diffuse, improving the adhesion between the grouting material and the substrate, thus increasing the bonding strength between the grout layer and the substrate.

[0004] However, in existing tunnel grouting processes, the heating jacket and the shell are an integral structure. When replacing the shell, the heating jacket must be replaced along with the shell, or it must be cut and separated, which is time-consuming, labor-intensive, and costly. Therefore, it does not meet the current needs. To address this, we propose a heating device for tunnel grouting processes. Utility Model Content

[0005] The purpose of this utility model is to provide a heating device for tunnel grouting process, so as to solve the problem mentioned in the background art that when heating is carried out in the existing tunnel grouting process, the heating sleeve and the shell are integrated structures. When replacing the shell, the heating sleeve needs to be replaced together, or it needs to be cut and separated, which is time-consuming, labor-intensive and costly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heating device for tunnel grouting process, comprising: a base, a mixing shell provided at the upper end of the base, a heating sleeve provided outside the mixing shell, the heating sleeve being detachable from the mixing shell, a control box provided on one side of the heating sleeve, an installation slot provided on the upper surface of the base, the lower end of the mixing shell being inserted into the installation slot, a pipe groove provided on one end surface of the base, and a drainage pipe inserted into the pipe groove.

[0007] Preferably, the bottom surface of the mounting slot is provided with a through-hole, which penetrates the base, and the tube groove communicates with the through-hole. The bottom end of the stirring shell is provided with a discharge pipe, which is inserted along the through-hole, and the discharge pipe is connected to the drain pipe through an interface with a valve.

[0008] Preferably, a limiting slot is provided on the outside of the mounting slot, and a limiting insert is provided at the bottom of the heating sleeve, with the limiting insert inserted into the limiting slot.

[0013] Preferably, each corner of the base is provided with a support leg, and the bottom of the support leg is provided with a caster wheel.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) This utility model sets a heating sleeve outside the mixing shell and sets an installation slot and a limiting slot on the upper surface of the base. The heating sleeve is put on the outside of the mixing shell, and then the bottom end of the mixing shell is inserted into the installation slot. The discharge pipe is inserted along the through hole to achieve a limiting effect, which prevents the mixing shell from shifting position and improves stability. The limiting plate at the bottom of the heating sleeve is inserted into the limiting slot to limit the heating sleeve, prevents position shift, and improves the stability of the connection between the heating sleeve and the mixing shell. When the mixing shell is damaged and needs to be replaced, the heating sleeve can be separated from the mixing shell by simply lifting the mixing shell, so as to replace the new mixing shell. No tools are needed for installation and disassembly, which saves time and effort, improves flexibility and convenience, and solves the problem that when heating is carried out in the existing tunnel grouting process, the heating sleeve and the shell are an integral structure. When replacing the shell, the heating sleeve needs to be replaced together or cut and separated, which is time-consuming, labor-intensive and costly.

[0016] (2) By setting a pipe groove on one side surface of the base, the pipe groove is connected to the through port, and a drain pipe is inserted inside the pipe groove. The discharge pipe and the drain pipe are connected through an interface with a valve. In this way, the part of the drain pipe that contacts the base plays a protective role, avoiding friction damage and improving safety and service life. Attached Figure Description
