The invention relates to the technical field of building equipment, in particular to a building plate painting device. The building plate painting device comprises a paint spraying box, a ventilatingdevice, a spray head mounting device, a spray head and a spray head lifting rod. The spray head lifting rod extends out of the paint spraying box rightwards, and is welded and fixed to a lifting block, the lifting block is mounted on a guide rail in a vertical sliding manner, and the right end face of the lifting block is welded and fixed to the left end of a connecting rod. The right end of the connecting rod is mounted on a lifting motor. A fixing mechanism is arranged at the bottom of a cavity in the paint spraying box, and mounted on a mounting base. A door is mounted on the front end faceof the paint spraying box through a hinge, and an observation opening is formed in the door. A hydraulic supporting seat and universal wheels are fixed to the lower end face of the paint spraying boxthrough bolts. The building plate painting device is simple in structure, existing equipment can be transformed conveniently, paint spraying operation on the two faces of a plate can be completed conveniently and fast at a time, and the plate painting efficiency is greatly improved; and high practicality is achieved, and the application range is wide.

The invention discloses an anti-falling tripod. According to the anti-falling tripod, structure design of an air bag assembly is adopted in a cavity of a support, when the tripod falls down, the support collides with the ground to enable a sensor component to generate impact induction, collision signals are transmitted to a control unit, the control unit controls a gas generator to instantaneouslygenerate a large amount of gas to enable air bag cushions to expand, the expanded air bag cushions are guided by guide plates and extend outwards in the circumferential direction of lining plates, sothat circumferential wrapping of the support devices such as a measurement instrument is formed instantly, the buffer protection effect of the device is achieved, the direct contact between the device and the ground is avoided, and therefore the functions of safety protection and anti-falling use of the supporting device are effectively achieved; and meanwhile, structure design with the fixing pointed ends capable of rotating is adopted, when the device is used for the ground with hard texture, and the fixing pointed ends can be rotated to enable the fixing pointed ends to be in a parallel state with the ground so as to be in horizontal contact with the ground so that the use function requirements of the tripod in different texture environments can be effectively realized.

The invention relates to a steel structure clamp, and relates to the technical field of building installation clamps. The steel structure clamp comprises a mounting base, a first support is arranged on the outer side wall of the mounting base, and a first clamping groove with an upward opening is formed in the first support; a sliding groove is formed in the mounting base, and a second support anda third support are slidably arranged in the sliding groove in the vertical direction; the top end of the second support penetrates out of an opening at the upper end of the sliding groove, and a second clamping groove is formed in the second support; the lower end of the third support penetrates out of an opening at the bottom of the sliding groove, and a third clamping groove with an upward opening is formed in the portion, penetrating out of the opening at the bottom of the sliding groove, of the third support; a pressing plate which penetrates out of a side opening of the sliding groove is formed in the upper end of the third support, and the pressing plate is located above the first clamping groove; and a fixing piece is arranged on the second support, the lower end of the fixing piece abuts against the pressing plate, and the fixing piece tightly presses the pressing plate on the first clamping groove. The steel structure clamp has the effects of being capable of meeting the mounting and fixing of multiple groups of steel structure cross beams at the same time, and stable in structure.

The invention relates to the technical field of packaging bag printing, and discloses a printing head buffer protection mechanism for color printing of packaging bags. The movable block has a support rod in the movable sleeve, a movable rod is arranged between the two support rods, and the two ends of the movable rod are respectively movably sleeved with the two support rods, and the two support rods are movably sleeved with a buffer spring , and the two ends of the buffer spring are respectively fixedly connected to the side walls of the movable block and the movable rod, the outer walls of both sides of the box body are provided with openings, and the openings are provided with reciprocating screw rods. The printing head buffer protection mechanism for color printing of packaging bags can buffer and protect the printing head as a whole, and can push the ink inside the printing head during the movement of the printing head to prevent it from accumulating on both sides of the box body, improving the performance of the printing head. The effect of subsequent printing.

The invention relates to the technical field of ancient building maintenance, and discloses a repairing and fixing device for cracks, which includes a frame and a workbench; two sets of limit components are relatively spaced and movably arranged on the workbench, and are suitable for being respectively fixed on the cracks On both sides of the limit assembly, any set of limit assemblies includes two relatively movable limit pieces; the first lifting mechanism is arranged between the limit assembly and the workbench, and is suitable for driving the limit assembly to move vertically relative to the workbench. Lifting movement. By setting two sets of limit components, each set of limit components includes two relatively movable limit pieces, relying on two sets of limit components to respectively fix both sides of the crack and fix the two surfaces on each side, The fixing effect is greatly improved, and the secondary damage to the repaired parts is effectively avoided. Use the first lifting mechanism to adjust the height of the whole device to adapt to the height of the parts to be repaired.

The invention relates to a buried self-helping respiring assistance assembly. The assembly comprises a protecting helmet and a protecting suit, a transition protecting layer is arranged in the circumferential edge of the protective helmet, the transition protecting layer is made from transparent materials, the upper end of the transition protecting layer is connected with a helmet body, the lowerend of the transition protecting layer is connected with a retracting sleeve member, the retracting sleeve member comprises an annular retracting airbag, an inflation pump and an inflation pipeline, and the inflation pump is connected with the annular retracting airbag through the inflation pipeline; a protecting effect can be achieved by the transition protecting layer on the helmet to prevent the mouth and the nose from being buried by soil and dust, the effects of inflating and retracting can be achieved by the retracting structure to ensure that an independent space can be formed in the assembly, the effect of buffering protecting can be achieved by an air collecting device, more importantly, air in the air collecting device can be provided for a person suffering from disaster, so thata respiring function is achieved, and the oxygen supplying of a user is ensured.
