Description

Technical Field

[0001] The utility model relates to a limiting device, in particular to a roller limiting device, and belongs to the technical field of tube labeling equipment. Background Art

[0002] The hoisting winch left by the mine construction unit is often used for lifting people and unloading materials during shaft equipment construction. However, the rope lowering point of the winch is often not in the same position as the rope lowering point during shaft equipment construction. There is a certain deviation angle. The maximum deviation angle of the wire rope between the original position of some winches and the position of the new rope lowering point during shaft equipment often exceeds the specification requirement (1°30′). In this case, the usual practice is to dismantle the original winch and then rearrange the winch according to the shaft equipment construction plan. This method will consume a lot of manpower and material resources and affect the construction period. In view of the above problems, the utility model proposes a new solution. Utility Model Content

[0011] Beneficial technical effects of the utility model:

[0012] 1. Compared with the traditional method of rearranging the winch, which requires 8-10 people and about 2 weeks of dismantling and installation, the installation of the limit device only requires 2-3 people and can be completed in 4 hours, saving a lot of manpower and time.

[0013] 2. Install the limit device without moving the winch and foundation, saving the foundation installation cost and machinery rental cost.

[0014] 3. The adopted limit device has simple processing form, low cost, can be reused, and is efficient and convenient to install.

[0015] 4. The limit device can adjust the limit length according to site needs.

[0016] 5. The limited installation does not involve high-risk and special operations such as large-scale lifting and concrete pouring. It is only carried out by bolt connection, which greatly reduces the safety risk.

[0017] 6. It is safe and reliable to use. There is no need to send someone to monitor it all the time. You only need to check the looseness of the bolts during daily maintenance. It is convenient and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0024] like Figure 1-Figure 4As shown, the roller limiting device provided in this embodiment includes a roller 1, a limiting ring 2 is provided on the outer side of the roller 1, and a plurality of evenly distributed connecting rods 3 are fixedly installed on the limiting ring 2, and the connecting rods 3 are connected to the roller 1 through the first fixing nut 4 and the second fixing nut 5. Compared with the traditional rearrangement of the winch, which requires 8-10 people and about 2 weeks of dismantling and installation, the installation of the limiting device only requires 2-3 people and can be completed in 4 hours, saving a lot of manpower and time: the limiting device is installed without moving the winch and the foundation, saving the basic installation cost and machinery rental cost: the processing form of the limiting device used is simple, the cost is low, and it can be reused, and the installation is efficient and convenient: the limiting device can adjust the limiting length according to the needs of the site: the limiting installation does not involve high-risk and special operations such as large-scale lifting and concrete pouring, and is only carried out by bolt connection, which greatly reduces the safety risk: it is safe and reliable to use, and there is no need to send people to monitor at all times. It only needs to check the looseness of the bolts during daily maintenance, which is convenient and practical.
