[0001] This utility model relates to the technical field of troweling devices, and in particular to a waterproof mortar troweling device. Background Technology
[0002] In the construction industry, waterproofing is a key aspect of ensuring the structural safety and functionality of buildings, and waterproof mortar application is an important part of this process. However, traditional waterproof mortar application methods have revealed many problems in long-term practice, seriously affecting the quality and efficiency of waterproofing projects.
[0003] For example, the existing technology authorization announcement number CN210315561U discloses a waterproof mortar troweling device for water construction, including a troweling plate with slightly raised sides. Two fixing plates are fixedly installed on the top of the troweling plate, and a shaft passes through the two fixing plates. A movable sleeve is movably sleeved on the shaft, and an installation block is fixedly installed on the movable sleeve. An installation rod is installed in the installation block.
[0004] However, it was found during the use of the device that it required manual operation, which greatly increased the labor intensity and reduced work efficiency when applying waterproof mortar to the wall. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a waterproof mortar troweling device that reduces the labor intensity of personnel in wall construction, improves work efficiency, enhances ease of use, and increases the flexibility of use.
[0006] This utility model discloses a waterproof mortar troweling device, comprising a troweling plate and a handle, the handle being installed on the outer wall of the troweling plate; it also includes a support device, a kit, multiple sets of telescopic rods, and multiple sets of springs. The kit is fitted onto the outer wall of the handle, and the troweling plate is detachably connected to the outer wall of the kit. Multiple sets of telescopic rods are all installed on the outer wall of the kit, and multiple sets of springs are respectively fitted onto the multiple sets of telescopic rods. The multiple sets of telescopic rods are installed on the support device, which is used to move the multiple sets of telescopic rods. The troweling plate is installed on the outer wall of the kit, and then the support device moves the multiple sets of telescopic rods horizontally, causing the telescopic rods to bring the troweling plate into contact with the wall surface. Then, the support device moves the multiple sets of telescopic rods up and down, thereby moving the troweling plate up and down to trowel the waterproof mortar on the wall surface. This reduces the labor intensity of wall construction and improves work efficiency. By setting multiple sets of springs, the elasticity of the troweling plate when in contact with the wall surface is improved, enhancing ease of use. When troweling is required on the ground or in confined spaces, the troweling plate can be disassembled, and personnel can grasp the handle to operate the troweling plate, improving flexibility of use.
[0007] Preferably, the support device includes a moving device, a base, a cross arm, a rack, a rotating shaft, gears, and a first motor. The base is slidably mounted on the moving device, and the cross arms slide through the base. Multiple sets of telescopic rods are mounted at the ends of the cross arms. Two sets of racks are respectively set on the outer walls of the two sets of cross arms. The rotating shaft is rotatably mounted on the outer wall of the base. Two sets of gears are respectively mounted on the outer wall of the rotating shaft and mesh with the two sets of racks. The first motor is mounted on the outer wall of the base, and the rotating shaft is connected to the output end of the first motor. The first motor drives the rotating shaft to rotate, which in turn drives the two sets of gears to rotate. After the two sets of gears rotate, they drive the cross arms to slide horizontally through the two sets of racks, thereby causing the trowel to move horizontally and contact the wall. Then, the moving device drives the base to slide up and down, thereby causing the trowel to move up and down.
[0008] Preferably, the moving device includes a driving device, a guide frame, a base, a reinforcing member, and multiple sets of support wheels. The base is slidably mounted on the guide frame via the driving device. The bottom end of the guide frame is connected to the top end of the base. The reinforcing member is disposed between the guide frame and the base. Multiple sets of support wheels are rotatably mounted on the base. The multiple sets of support wheels support and move the base, thereby facilitating the application of waterproof mortar to different locations on the wall using a trowel.
[0009] Preferably, the driving device includes a lead screw and a second motor. The lead screw is rotatably mounted between the guide frame and the base, and the base is screwed onto the lead screw. The second motor is mounted on the top of the guide frame, and the output end of the second motor is connected to the lead screw. The second motor drives the lead screw to rotate, thereby driving the base to slide up and down.
[0010] Preferably, it also includes multiple sets of connectors and multiple sets of bolts. The multiple sets of connectors are all set on the outer wall of the kit, and the multiple sets of bolts pass through the multiple sets of connectors. The outer wall of the trowel plate is provided with threaded holes. The multiple sets of bolts are installed on the threaded holes of the trowel plate by passing through the multiple sets of connectors, which improves the convenience of loading and unloading the trowel plate.
[0011] Preferably, the outer wall of the handle is provided with an anti-slip pad to improve the convenience of hand operation.
[0012] Preferably, a battery is provided on the base; this reduces the impact of the device's use being limited by the length of the power cord.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The trowel is installed on the outer wall of the kit, and then multiple sets of telescopic rods are moved horizontally by the support device, so that the telescopic rods bring the trowel into contact with the wall. Then, the support device drives the multiple sets of telescopic rods to move up and down, so that the trowel moves up and down to trowel the waterproof mortar on the wall. This reduces the labor intensity of personnel in wall construction and improves work efficiency. By setting multiple sets of springs, the elasticity of the trowel when in contact with the wall is improved, and the convenience of use is improved. When it is necessary to trowel the ground or a small space, the trowel can be disassembled and the personnel can grab the handle to operate the trowel, which improves the flexibility of use.
