This utility model relates to the field of tension adjustment devices, and in particular to a tension adjustment device for a belt feeder. It includes an initial positioning component and a belt feeder tail end. An adjustment component for adjusting tension is located on the outer side of the belt feeder tail end. A sound comb tooth that emits a prompting sound upon triggering is fixedly installed on the front of the belt feeder tail end. An annular scale with staggered markings is located on the front of the belt feeder tail end. The adjustment component has a raised point for triggering the sound and a pointer for calibration positioning on its exterior. By cooperating with the raised point, the sound comb tooth bends upon contact with the raised point and generates a sound upon rebound, effectively indicating the number of turns of the screw to be rotated. Combined with the positioning assistance of the annular scale and pointer, no measuring tape is required for calibration, and deviations are less likely to occur, ensuring the balance of tension on both sides of the conveyor belt.

The present disclosure relates to the technical field of template reinforcement, and one embodiment of the present disclosure provides a template reinforcement device which is applied to a template and further comprises a T-shaped strip, sponge strips, sealing strips, tensioning mechanisms, moving plates and close-together mechanisms. The T-shaped strip is located at the splicing position of two templates. Two sponge strips are provided, and the two sponge strips are respectively fixed to the two sides of the T-shaped strip. The two sponge strips are both fixedly connected with sealing strips. The two sealing strips are respectively in contact with the two templates. Two tensioning mechanisms are provided, and the two tensioning mechanisms are respectively located at the two templates. Two moving plates are provided, and the two moving plates are arranged on one side of the T-shaped strip through a moving mechanism. The two moving plates are both provided with close-together mechanisms. Through the above technical solution, the technical problem that the splicing position of two templates is prone to deviation when the template is reinforced, thereby affecting the reinforcement effect of the template and further affecting the effect of concrete pouring is solved.

The utility model discloses a vertical drilling machine which comprises an installation frame, a drilling machine body arranged on the installation frame in an up-down sliding mode, a feeding mechanism driving the drilling machine body to slide up and down, a clamping mechanism clamping a steel rail during drilling and a positioning mechanism. The clamping mechanism is arranged on the mounting frame in a vertical sliding mode, the positioning mechanism is provided with a positioning face abutting against the end face, to be drilled, of the steel rail during drilling, a positioning hole penetrating through the positioning mechanism is formed in the positioning mechanism, the position of the positioning hole corresponds to that of the drill bit, the central axes of the positioning hole and the drill bit are collinear, and the diameter of the positioning hole is larger than the diameter of the drilled hole. The drilling machine is high in positioning speed, high in efficiency and high in precision during drilling. And the drilling machine can be fixed to the steel rail through cooperation of the positioning mechanism and the clamping mechanism, so that the drilling machine is fixed stably, the shaking phenomenon is not likely to occur in the drilling process, the drilling position is not likely to deviate in the drilling process, and the drilling position precision can be further guaranteed.
