The invention discloses a cast-in-place bridge reinforcing steel bar auxiliary installation device, and relates to the technical field of reinforcing steel bar installation, the cast-in-place bridge reinforcing steel bar auxiliary installation device comprises an installation seat, a concentric-square-shaped supporting frame is fixed on the installation seat, a pair of semi-circular-ring plates is slidably installed on the concentric-square-shaped supporting frame, and a semi-circular-ring pipe is fixed on each semi-circular-ring plate; the arc-shaped rack is in transmission connection with a radial traction assembly used for driving the radial fixing plate to slide in the radial direction. The two semicircular ring pipes are driven by the opposite sliding assembly to achieve butt joint, the function of free butt joint and separation greatly facilitates installation, a reinforcement cage needing to be installed is encircled by the two semicircular ring pipes, the clamping assembly is driven by the radial traction assembly, effective butt joint of vertical steel bars of the reinforcement cage is achieved, and the installation efficiency is improved. The one-way locking assembly facilitates radial uniform traction of the reinforcement cage, stable positioning of the cast-in-place bridge reinforcement cage is guaranteed, deformation and deviation of the reinforcement cage are effectively avoided, and the mounting and positioning quality of the reinforcement cage is greatly improved.

The utility model relates to the technical field of servo motors, in particular to a power supply wiring mechanism for a servo motor, which comprises a first shell and a second shell. A front end cover and a rear end cover are arranged at the two ends of the first shell respectively, and the front end cover, the first shell and the rear end cover are connected with one another to form a first mounting cavity; the second shell comprises a sleeving part and a shell part, a fan cover is arranged at the rear end of the second shell, and a second mounting cavity is formed among the fan cover, the shell part and the rear end cover; a junction box with a third mounting cavity is arranged on the outer wall of the second shell; a first wire hole is formed in the side wall of the first shell, a second wire hole is formed in the side wall of the second shell, and a third wire hole is formed in the bottom wall of the junction box. The mechanism not only is simple in structure, but also can gather the wire harnesses of the first mounting cavity and the second mounting cavity into the junction box at the top, so that the unified wiring operation with the outside is more convenient.

The application discloses an air bag mattress and bed. The air bag mattress comprises a mattress body, an air pump assembly, an air bag assembly, a heating element and a control device. The mattress body is provided with a headrest area, a neck area and a body area; the air pump assembly comprises two independent air pumps; the air bag assembly comprises two air bags corresponding to the headrest area and the neck area respectively, and the air pump is connected to the corresponding air bag through a pipeline; the heating element is integrated in the neck air bag; the control device is electrically connected to the air pump assembly and the heating element, and can control the inflation of the neck air bag and the hot compress of the heating element, and automatically switches to the inflation of the headrest air bag after a preset time, so that the switching of the cervical vertebra hot compress and the sleep support is realized. The air bag mattress and bed disclosed by the application can realize the hot compress positioning of the cervical vertebra through the air bags controlled independently in different areas, and effectively improve the use experience of users.

A wafer rotary table is rotatably installed on a bottom plate, a rotary table driving device for driving the wafer rotary table to rotate is arranged on the bottom plate, the wafer rotary table comprises an upper disc located at the bottom and a shell surrounding the upper disc, a lifting and leveling device is installed on the upper disc, a workbench is installed on the lifting and leveling device, and the lifting and leveling device is connected with the workbench. A wafer placing table is installed on the working table, a lifting and leveling device drives the wafer placing table to lift and level, an ejector pin which penetrates through the wafer placing table and is used for supporting wafer lifting is installed on the upper disc in a lifting mode, the ejector pin is driven by an ejector pin lifting power device, and a plurality of bottom measuring sensors which penetrate through the wafer placing table in a lifting mode are further arranged on the upper disc. The wafer placing table is provided with a negative pressure channel for performing negative pressure suction on the wafer, and the negative pressure channel is connected with a negative pressure system; the adjusting table can perform horizontal adjustment and height measurement on the supported wafer, and can ensure that the wafer is accurately placed after being taken for multiple times, so that the use effect is improved.

The adjustable calcaneus traction support comprises a horizontal supporting bottom frame, a shank supporting plate and an ankle supporting plate are sequentially arranged on the horizontal supporting bottom frame in a supporting mode, the bottom of the ankle supporting plate is horizontally and rotatably installed on a first supporting block around the axis, and the first supporting block is vertically and movably installed on a second supporting block; the second supporting block is horizontally and movably installed on the horizontal supporting bottom frame in the extending direction of the legs. The technical scheme is mainly applied to patients needing calcaneus traction.

The present invention relates to the technical field of cloth processing and feeding equipment, and specifically discloses an automatic feeding device and method for an ultrasonic lace machine, comprising a conveying structure, a fixing structure, a traction structure and a limiting structure; the fixing structure is detachably arranged on the rear side of the left end of the conveying structure, the traction structure is fixedly arranged on the conveying structure, and the limiting structure is fixedly arranged on the traction structure. The present invention can continuously and stably provide cloth for the lace machine through an automated structure that simulates manual pushing and flattening of cloth feeding, which can greatly improve the continuity of production, thereby improving production efficiency. The automated structure can stably push and flatten cloth according to a set program, so that the state of each section of cloth when entering the lace machine is relatively consistent, thereby improving the stability of product quality.
