The present application relates to a kind of liftable scaffold, including operating platform and the scaffold assembly for supporting operating platform, scaffold assembly includes the support frame being respectively arranged in the both sides of operating platform and the adjusting mechanism installed on support frame, operating platform is provided with the lifting sliding sleeve of sliding sleeve in support frame, adjusting mechanism includes limiting assembly and lifting assembly, limiting assembly is used to lock lifting sliding sleeve on support frame, lifting assembly is connected with operating platform and can drive operating platform to lift, the purpose of the present application is to provide a kind of liftable scaffold, to solve the technical problems that the unlocking state of existing liftable scaffold cannot be kept, lifting is laborious, hole position is difficult to align.

The utility model discloses a large water conservancy gate easy to open, which belongs to the technical field of water conservancy projects and comprises a gate-type frame and gate grooves arranged on the inner side of the gate-type frame, a hoist is mounted at the top of the gate-type frame, a screw rod is vertically mounted in the hoist, and gate leaves are vertically arranged between the two groups of gate grooves in a sliding manner. The baffle is vertically arranged in the gate leaf in a sliding mode, the spring is arranged between the top end of the baffle and the sliding groove, the spring is located on an elongated rotary table when the gate leaf is closed, and the top end of the baffle is directly connected with the screw rod through the rectangular sliding rod, so that in the using process of the device, the gate leaf is not prone to falling off. By means of the lifting structure composed of the hoist and the screw rod, when the gate is opened, the baffle is lifted firstly and then the gate leaf is lifted, opening control over the gate is more convenient, and when the baffle is controlled to be lifted, the baffle is lifted in a more labor-saving mode through the reset acting force of the spring; the first through groove and the second through groove can be conducted more quickly to complete switching-off.

This utility model discloses a conveying device for garment production, including two side frames. An upper belt conveyor and a lower belt conveyor are located between the side frames for forward and backward transport. A front lifting platform is located between the side frames, and a first linear reciprocating motion mechanism is mounted on the front lifting platform. Two front side plates are symmetrically arranged on the front lifting platform. A front driving belt roller and a front driven belt roller are rotatably connected between the front side plates. A front belt is drive-connected between the front driven belt roller and the front driving belt roller. A front driven clutch wheel is located at one end of the front driving belt roller, and a front driving clutch wheel is located directly above the front driven clutch wheel. A first power assembly is drive-connected to the front driving clutch wheel. This conveying device, by using two sets of lifting mechanisms in combination, can reposition the plastic frames containing garments, achieving a circulating effect of the plastic frames on the upper and lower belt conveyors. The overall function is complete and highly practical.

This utility model belongs to the technical field of construction equipment and discloses a movable precast beam vertical reinforcement positioning device, including a base, a detachable enclosure connected to the base, a support connected to the enclosure, a rotating shaft connected to the support, a motor connected to the support, the motor output end connected to the rotating shaft, a connecting rope connected to the rotating shaft, a fixed pulley assembly connected to the enclosure, the connecting rope passing through the fixed pulley assembly and connecting to a positioning plate, the positioning plate being slidably connected to the enclosure, the positioning plate having positioning holes and a pouring opening, and the base having positioning grooves that mate with the positioning holes. This utility model can comprehensively prevent the reinforcement from lateral bending due to its own weight or the force of concrete vibration, ensuring the verticality and positional accuracy of the reinforcement, and also prevent it from being poured into the concrete, thus affecting the strength of the precast beam.
