Description

Technical Field

[0001] The utility model relates to the technical field of hole supporting devices, in particular to a stable hole supporting device. Background Technique

[0002] Construction engineering refers to the engineering entity formed by the construction of various housing buildings and their ancillary facilities and the installation of supporting pipelines and equipment. Among them, "housing building" refers to a project with a roof, beams, columns, walls, foundation, and capable of forming an internal space to meet the needs of people's production, residence, study, and public activities. Building reserved holes are common structures in buildings. The purpose is to prevent the reserved holes from being blocked. During wall construction, the vibration generated during construction is likely to cause the collapse of the hole wall.

[0003] Currently, in the prior art, most hole supporting devices do not have an extension device. Therefore, when construction workers operate the hole supporting device, once they encounter a hole with a relatively deep opening, they need to reach their hands into the hole to deploy the hole supporting device. In the narrow hole, when the construction workers put their hands in, it is very easy to cause injuries due to friction with the hole wall, and it is extremely difficult to control the hole supporting device with the hands in the narrow space. In view of this, we propose a stable hole supporting device. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a stable hole supporting device, which can solve the problems raised in the above technical background.

[0005] To achieve the above purpose, the utility model proposes a stable hole supporting device, including a device main body, and a spreading structure is arranged on the surface of the device main body. The spreading structure includes

[0006] An outer connecting ring, the inner wall of the outer connecting ring is rotatably connected with a nut, the inner wall of the nut is threadedly connected with the surface of the device main body, the inner wall of the outer connecting ring is hinged with one end of a long connecting rod, and the other end of the long connecting rod is hinged with the inner wall of a support plate.

[0007] Preferably, one end of a short connecting rod is hinged with the inner wall of the support plate, and the other end of the short connecting rod is hinged with the inner wall of the device main body. By setting the short connecting rod, when the long connecting rod pushes the support plate to expand, the short connecting rod can limit the other end of the support plate, so that the support plate is in a vertical state throughout the expansion process, thus having a better supporting effect on the inner wall of the hole.

[0008] Preferably, the device main body includes a handle, one end of the handle is fixedly connected with one end of a central column, and the other end of the central column is fixedly connected with the upper surface of a connecting plate.

[0009] Preferably, a threaded sleeve is sleeved on the surface of the center column, and a toothed disc is fixedly connected to the upper surface of the threaded sleeve.

[0010] Preferably, the surface of the toothed disc meshes with the surface of the helical gear, and the surface of the helical gear is rotationally connected to the surface of the center column.

[0011] Preferably, the bevel gear is connected to the hand wheel via a belt drive, and the surface of the hand wheel is rotationally connected to the surface of the center column.

[0012] Preferably, the surface of the hand wheel is rotatably connected to the surface of the center column.

[0013] Beneficial Effects

[0014] The utility model provides a stable hole support device, which has the following beneficial effects:

[0015] (1) The stable hole support device is equipped with a hand wheel. When the hole needs to be supported, the device body is inserted into the hole. The hand wheel is turned to drive the bevel gear to rotate through the belt. The rotation of the bevel gear drives the toothed disc to rotate, so that the threaded sleeve rotates, thereby supporting the inner wall of the hole through the expansion of the support structure. By extending the belt, workers can avoid using the support device in a narrow hole, thereby greatly speeding up the construction time.

[0016] (2) The stable hole support device has a nut which is arranged so that when the threaded sleeve rotates, the nut pushes the outer connecting ring to move downward, thereby pushing the support plate to expand outward through the long connecting rod, thereby supporting the inner wall of the hole and preventing the hole from collapsing. The self-locking property of the threaded sleeve and the nut makes the device more secure when used. BRIEF DESCRIPTION OF THE DRAWINGS

Then, the surface of the handwheel 107 is rotationally connected to the surface of the center column 102. Through the handwheel 107, when the hole needs to be supported, the device body 1 is inserted into the hole. By rotating the handwheel 107, the handwheel 107 drives the bevel gear 105 to rotate through the belt 106. The rotation of the bevel gear 105 drives the toothed disc 104 to rotate, so that the threaded sleeve 103 rotates, thereby supporting the inner wall of the hole through the expansion of the support structure 2. By extending the belt 106, workers can avoid using the support structure 2 inside a narrow hole, thereby greatly speeding up the construction time.

[0025] The surface of the device body 1 is provided with a support structure 2, which includes: an outer connecting ring 201, the inner wall of the outer connecting ring 201 is rotatably connected with a nut 202, and through the provided nut 202, when the threaded sleeve 103 rotates, the nut 202 pushes the outer connecting ring 201 to move downward, thereby pushing the support plate 204 to expand outward through the long connecting rod 203, thereby supporting the inner wall of the hole to prevent the hole from collapsing, and because of the self-locking property of the threaded sleeve 103 and the nut 202, the device is more secure when used, and the inner wall of the nut 202 is screwed to the surface of the device body 1. The inner wall of the outer connecting ring 201 is hinged to one end of the long connecting rod 203, the other end of the long connecting rod 203 is hinged to the inner wall of the support plate 204, the inner wall of the support plate 204 is hinged to one end of the short connecting rod 205, and the other end of the short connecting rod 205 is hinged to the inner wall of the device body 1.
