Reinforcing is conducted through the steel frame cover arch, and the stability of the lining upper structure is improved; the shock insulation support is arranged on the inner surface of the primary support, uneven deformation, caused by shock, of a surrounding rock-structure is effectively reduced, the lining structure can better adapt to deformation of the surrounding rock, the shock resistance of a traffic tunnel under the action of strong shock is improved, and safe operation of a lifeline of the traffic tunnel is guaranteed.

This invention discloses a bar forging cutting device with cleaning function, including a machine body. Through the coordinated use of a limiting mechanism, a transfer mechanism, a closing mechanism, a clamping mechanism, an auxiliary mechanism, and a cutting mechanism, this invention enables the cutting of bar forgings of different lengths and outer diameters according to requirements. It also automates the process by classifying and conveying the two sets of forgings separated after cutting. Furthermore, it allows for the centralized collection and cleaning of debris generated during cutting. When cutting forgings shorter than the "dead zone," the invention fixes the rear end of the forging, while the front end abuts against two sets of fitting auxiliary plates. The top of the forging is first cut to form a "notch," and then a pressure plate enters the "notch" and engages with the outer walls of the two sets of fitting auxiliary plates, preventing the cut forging from falling off. It can also be transferred by two sets of clamping components, making the process convenient and quick.

The invention belongs to the technical field of drying devices, and particularly relates to a betel nut circulating drying device which comprises a conveying structure, the conveying structure is used for conveying betel nut fruits and comprises a conveying belt, and a drying structure is arranged at one end of the conveying belt. By arranging a movable plate and a collecting mold, when betel nuts are dried, the betel nuts firstly fall on the surface of a transfer crawler belt to be dried, and along with rotation of the transfer crawler belt, the betel nuts fall on the surface of the collecting mold and vertically fall into a placing groove, so that the surfaces of the betel nuts can be comprehensively dried; and when the collecting mold moves to the lower end of a collecting crawler belt, a buckle can automatically block an opening of a containing groove, so that the areca nuts cannot fall off, the collecting mold is in sliding connection with a clamping plate, after the areca nuts are dried, only the collecting mold needs to be taken out from a plate outlet, and a new collecting mold can also be fed from a plate feeding opening, so that the drying efficiency is greatly improved. Therefore, the betel nuts are circularly treated.

The present disclosure provides an indoor unit installation system, an indoor unit and an air conditioner, wherein the installation system includes: a wall-mounted plate for connecting to the indoor unit; one end of a connecting rod assembly is connected to the wall-mounted plate, and the other end is connected to the wall; the connecting rod assembly includes a folded state and an unfolded state. In the folded state, the connecting rod assembly can fix the indoor unit on the wall; in the unfolded state, the connecting rod assembly can support the indoor unit so that the indoor unit forms a first preset angle and / or a first preset distance with the wall. The indoor unit installation system disclosed in the present disclosure can enable the indoor unit to have a larger flipping and / or translation space, and expose the connection pipe operation area behind the indoor unit to facilitate after-sales personnel to connect the pipes. It is easy to use, and the machine body will not fall due to excessive flipping angles, and it is safer.

The present invention relates to a concrete block handling and compression test system, which has a maintenance station, a test station, and a handling station. The maintenance station includes a placement bracket, and the test station is provided with a test device; the handling station includes a handling device, and the handling device includes a mobile platform driven by a driving motor, a sliding platform relatively arranged at both ends of the mobile platform, and an adjustment rod driven by a second motor to rotate and arranged on the corresponding sliding platform. The sliding direction of the sliding platform is perpendicular to the moving direction of the mobile platform. Each adjustment rod is provided with a clamping plate relatively arranged and used to take and place concrete blocks. The clamping plates on each adjustment rod are respectively lifted and arranged on the corresponding adjustment rod by two driving cylinders. Each clamping plate is arranged parallel to the upper surface of the mobile platform, and the two relatively arranged clamping plates and the adjustment rod form a clamping cavity for clamping concrete blocks. The present invention can automatically carry out the handling, transfer and testing of concrete blocks, which is practical and efficient.
