The invention relates to a chain connecting link, which has two link brackets (4, 5) coupled via their limbs (6, 9), and a bar (14a-14c) that is inserted transversely between the limbs (6, 9) of the link brackets (4, 5). One limb (6) of each link bracket (4, 5) comprises a neck section (7) and a journal (8) thicker than the neck section, and a neck recess (10) and a journal recess (11) are provided in a matching fashion at the other limb (9) of the link bracket (4, 5). According to the invention, conically configured flank surfaces (12) with respect to the vertical central longitudinal plane (MLE) are provided at each journal (8) and at each journal recess (11).

The invention relates to a bearing test device capable of applying radial alternating load based on a lead screw transmission mechanism. The bearing test device comprises a computer which is connectedwith a driving motor. The output shaft of the driving motor is connected with a rotating shaft through a coupler. The rotating shaft is externally sleeved by a detected bearing which is a sliding bearing. The bearing test device also comprises a radial alternating load loading module which is arranged on the detected bearing. The radial alternating load loading module comprises a temperature sensor which is arranged on the detected bearing and loading parts which are arranged on the external side of the detected bearing and symmetrical in the four directions. Each loading part comprises a rotating motor, the lead screw transmission mechanism which is connected with the rotating motor, a spring which is connected with the lead screw transmission mechanism and a connecting mechanism which is connected with the other end of the spring. Compared with the devices in the prior art, loading of the alternating load of four directions and two radial directions on the bearing can be realized.

The invention discloses a ceramic tile carrying device for a construction site, and relates to the field of building facilities. The ceramic tile carrying device comprises a transfer mechanism and a shelf mechanism, wherein a slide plate which can be detachable and can adjust spacing is arranged on the shelf mechanism; a cushion block which is detachable with the slide plate is arranged on the slide plate; the cushion block is of a steel wire cotton structure; acting force between the cushion block and the slide plate is transmitted through a spring; the transfer mechanism comprises a car body; a lifting frame capable of lifting is arranged on the car body; and an L-shaped fork frame which is matched with the rack mechanism for use is arranged on the lifting frame. The ceramic tile carrying device has the beneficial effects that: damages, on ceramic tiles, of big and small vibrations caused by road bumps in the way are avoided, and the construction cost is greatly reduced; and the ceramic tile carrying device has very strong universality, and is suitable for carrying various ceramic tiles and related friable materials.

The invention discloses a tower escaper apparatus which comprises a bearing fixing support, a rope winding device, a riding accommodation device and a descending control device. The coiling device comprises a shell and a winding roll, the winding roll is wound with a bearing rope, and the rope winding device is suspended on the bearing fixing support through a free end of the bearing rope; the riding accommodation device is fixedly connected below the shell; and the descending control device comprises a friction brake and a descending operation handle which are tightly clasped to the winding roll in a normal state, and the descending operation handle is in transmission fit with the friction brake. When in use, the bearing fixing support is arranged on a window or a balcony or other places, a person can control the friction braking force of the friction brake to the winding roll through the descending operation handle so as to control the descending speed of the riding accommodation device to be in a safety range, and meanwhile, ground staff can unlock the winding roll through a reset unlocking mechanism and remotely control a motor through a remote controller to drive the winding roll to rotate so as to ensure that the riding accommodation device returns to a high place and can be used by other people for escape. In addition, the invention is comfortable in use and suitable for various people.

The invention relates to a fixing base, in particular to a steel wire pull rope fixing base. One end of a steel wire pull rope can be tightened on a device; the left and right ends of the device can be tightened into the steel wire rope; and the steel wire pull rope can be pulled by a slight distance after straightening for specific conditions of the steel wire pull rope in actual use. A base rodinner groove is formed in a base rod; convex edges are arranged on the front and back inner sides of the upper end of the base rod; a middle slide block is slidingly connected between the two convex edges; the left and right ends of the middle slide block are fixedly connected with spring sleeve rods; two spring stoppers are symmetrically arranged at the left and right ends in the base rod inner groove; the outer ends of the two spring sleeve rods are slidingly connected to the two spring stoppers; springs sleeve the two spring sleeve rods; the springs are positioned between the middle slide block and the spring stoppers; two round rail rods are provided; round rail rod edge bases are fixedly connected to the left and right ends of the round rail rods; and the two round rail rods are fixedly connected to the front and back ends of the base rod through the round rail rod edge bases.
