This utility model provides an anti-slip device for a mining ore conveyor belt. It features a conveyor belt with multiple baffles along its length and width. The baffles effectively block the transported ore, preventing it from sliding under gravity when the conveyor belt is tilted, thus ensuring normal transport. Multiple reinforcing ribs on both sides of the baffles prevent bending under external forces. Countersunk holes on the conveyor belt prevent friction between the bolt ends and the conveyor belt support rollers. The device is simple in structure, convenient in use, and low in cost.

A lifting motor is provided at the lower end of the lifting mounting plate. The output shaft of the lifting motor is connected to the lead screw. A slider is screwed onto the lead screw. A rotating mounting plate is fixed on the slider. A hollow rotating platform is provided on the rotating mounting plate. A faucet is provided at the upper end of the hollow rotating platform. The faucet extends upward along the lifting mounting plate and moves through the lifting mounting plate. A photoelectric sensor is provided on the side of the hollow rotating platform. A baffle is rotatably provided on the hollow rotating platform. Lifting and rotation are controlled separately by the lifting motor and the rotating motor. After the lifting motor controls the faucet to rise, the rotating motor controls the faucet to rotate 90 degrees. The faucet can be manually rotated at any angle according to usage requirements.

This utility model discloses a ceramic substrate slag scraping operating table, comprising: a base; a slag collection area disposed at one end of the upper surface of the base for collecting slag; a placement ramp disposed at the other end of the upper surface of the base and inclined towards the slag collection area for placing the ceramic substrate; and a bottom support structure protruding from the bottom end of the placement ramp, wherein during slag scraping, the lower end of the ceramic substrate presses against the bottom support structure and is placed against the placement ramp. This application has a simple structure. Through the coordinated arrangement of the placement ramp and the slag collection area, during slag scraping, the ceramic substrate is simply placed flat on the placement ramp, and then a cleaning tool is used to scrape the slag directly into the slag collection area along the direction of the placement ramp, achieving automatic slag collection, greatly improving cleanliness, protecting the environment, and preventing damage to the ceramic substrate from impacts with the slag. It is practical and convenient.

A measuring device for leak testing of fuel tanks includes a locking unit and a leak testing unit. The locking unit includes a fixed base plate, a cylinder support frame, a drive cylinder fixedly installed above the cylinder support frame, a clamping slide plate for mounting the fuel tank to be tested, and two symmetrically arranged first L-shaped support plates. The first L-shaped support plates are composed of a transverse plate and a longitudinal plate. The transverse plate has an upper mounting hole. The fixed base plate has multiple stop holes adapted to the upper mounting hole. The multiple stop holes are arranged in a transversely uniform array. The mounting hole and one of the stop holes are fixedly connected. The upper inner side of the longitudinal plate has a side sliding groove. Two side sliding grooves form a sliding groove. The sliding groove and the clamping slide plate are adapted to slide. The front end of the sliding groove has a sliding opening for the clamping slide plate to slide out. The lower end of the drive cylinder has an airtight pressure head that can seal and adapt to the fuel tank opening. The leak testing unit includes the airtight pressure head and an airtightness testing instrument connected to the airtight pressure head.

This utility model discloses a portable solar lamp chassis and a portable solar lamp including the chassis. The lamp includes a battery, a light source plate, and a lamp chassis. The lamp chassis includes a chassis body; a handle hinged to the chassis body; a battery mounting structure on the chassis body; and a light source plate fixing structure, including a plurality of first connecting posts and a plurality of second connecting posts on the chassis body, and circular and elliptical connecting holes respectively opened on the first and second connecting posts. The battery is installed and fixed by the battery mounting structure, eliminating the need for glue application and facilitating multiple disassembly and assembly. Simultaneously, the combined arrangement of the circular and elliptical connecting holes allows screws to be connected to multiple positions of the elliptical connecting holes during light source plate assembly, thereby changing the fixing distance between the first and second connecting posts and adapting to light source plates of different sizes, making it practical and convenient.

The utility model belongs to building repair structure technical field, concretely is a kind of post-fire concrete column damage repair reinforcing structure of multi-unit, set in concrete column outside, include: fixed subassembly and set on the repair subassembly of fixed subassembly;The fixed subassembly includes the fixed plate fixed around in the bottom of concrete column and the limiting plate set in the fixed plate outside;The repair subassembly includes the outer protective steel sheet inserted in the limiting plate, the positioning bolt installed in the outer protective steel sheet top, the mounting hole opened in the outer protective steel sheet top.The utility model can surround the outer protective steel sheet in the outside of concrete column by repair subassembly, then pour concrete to its inside, remove fixed bolt and vibration head after concrete solidification, to form a hole for the outer protective steel sheet fixed in the outside of concrete, the practicality of bolt body is convenient, so not only realize repair, but also use outer protective steel sheet to play subsequent fireproof function, and the practicality is higher.

The utility model discloses a coating dispersing and stirring machine which comprises a base, the dispersing barrel is movably arranged on the base; the dispersing and stirring mechanism is movably arranged above the dispersing barrel; the sleeve rod seat is arranged on the base and located on one side of the dispersing barrel, a lifting rod is arranged on the sleeve rod seat in a sliding and sleeving mode, and a hydraulic driving assembly is further arranged on the base; the connecting seat is arranged on the loop bar seat, and a locking mechanism is arranged on the connecting seat in a sliding manner; and the adjusting structure is arranged between the connecting seat and the locking mechanism. During dispersing and stirring, the dispersing barrel with the corresponding size can be selected and moved to the corresponding station on the base according to the actual specific situation, then the locking mechanism is moved to be attached to the side wall of the dispersing barrel and fixed through the adjusting structure, and then the dispersing barrel is locked through the locking mechanism, so that fixing of the dispersing barrel can be completed, the applicability is wide, and the practicability is high.
