Description

Technical Field

[0001] The utility model belongs to the technical field of paper-faced gypsum board production equipment, in particular to a locking device for a joint bearing of a two-control lifting frame. Background Art

[0002] Paper-faced gypsum board has the characteristics of light weight, sound insulation, heat insulation, strong processing performance and simple construction method. It is one of the new lightweight panels with good development prospects. Gypsum board has been widely used in interior partitions, ceilings, decorative panels and sound-absorbing panels of residential, office buildings, shopping malls and other buildings.

[0003] On the gypsum board production line, after the gypsum board is formed, it needs to be sent to the dryer for dehydration and drying. The horizontal conveying lifting frame is responsible for conveying the gypsum board into the dryer. There are four fulcrums on the legs of the lifting frame. The fulcrums are connected to the bearings by pins. In daily production, the bearings are usually locked and fixed by top screws. However, due to the long-term operation of the equipment, the top screws of the glands may break and the joint bearings may fall off, causing equipment failure.

[0004] Therefore, how to provide a locking device that can effectively lock the bearing without causing the bearing to fall off or the top screw to break is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0005] The utility model aims to provide a two-control lifting frame joint bearing locking device to solve the technical problems of poor locking effect and easy breakage of traditional bearing locking devices.

[0006] In order to solve the above technical problems, the specific technical solutions of the utility model are as follows:

[0007] In some embodiments of the present application, a two-control lifting frame joint bearing locking device is provided, comprising:

[0008] A pin shaft, wherein one end of the pin shaft is provided with a first threaded portion, the other end of the pin shaft is provided with a second threaded portion, and a receiving portion is provided thereon;

[0009] A bearing, wherein the bearing is disposed on the receiving portion of the pin and is fixedly connected to the pin;

[0010] A stopper component, which is sleeved on the accommodating portion and is slidably connected to the pin shaft;

[0011] A locking component, wherein the locking component is disposed on the second threaded portion and is threadedly connected to the pin;

[0012] After the first threaded portion of the pin shaft is installed at a specified position, the locking component is rotated to make it contact with the withdrawal stop component, so that the withdrawal stop component contacts the bearing and clamps the bearing.

[0013] In some embodiments of the present application, the pin shaft is further provided with symmetrically arranged keyways between the first threaded portion and the accommodating portion.

[0014] In some embodiments of the present application, the backstop component is an integrated structure, including:

[0015] A support component is provided with a through hole inside the support component, which is sleeved on the accommodating portion of the pin shaft, and a support leg piece arranged in a ring array is provided on the support component.

[0016] In some embodiments of the present application, the leg member and the supporting component are arranged obliquely.

[0017] Compared with the prior art, the beneficial effect of the utility model lies in that the pin shaft is installed at the corresponding position by means of thread locking, and a stop member is added to the pin shaft, and the locking member is moved on the second threaded portion, so that the stop member contacts the bearing and the bearing is in a clamped state. By adding the stop member, direct contact between the bearing and the locking member is avoided, thereby reducing the wear of the locking member, and avoiding the problem of breakage of the locking member and the falling off of the bearing.
