Description

Technical Field

[0001] The invention relates to the technical field of engineering project management, and in particular to a construction safety warning device for engineering project management. Background Art

[0002] An engineering project is a project that uses engineering construction as a carrier and is a one-time engineering construction task that is managed. It takes buildings or structures as target outputs, requires payment of a certain fee, follows certain procedures, is completed within a certain period of time, and must meet quality requirements. During the construction of engineering projects, there are various dangerous areas at the construction site, such as the entrance to the construction site, construction lifting machinery, tunnel entrances, bridge entrances, foundation pit edges, explosive storage areas, and hazardous gas and liquid storage areas. Due to the danger of their own operations, these areas need to be targeted and obvious safety warning signs must be hung in the dangerous areas to warn passing construction personnel, vehicles, etc. to avoid accidents.

[0003] There are the following technical problems with the currently used construction safety warning devices for project management:

[0004] 1. The warning device is installed near construction equipment, busy traffic areas, or mechanical equipment. Long-term vibration and impact will gradually loosen the fixing parts of the sign.

[0005] 2. Temporary warning devices need to be frequently relocated. During the insertion process, it is easy to encounter hard materials such as brick fragments and clay minerals in the soil. Ordinary insert-type supports make it difficult to smoothly insert the support rod into the ground to achieve the purpose of stable support. Forced insertion may even damage the support rod. Summary of the invention

[0006] The purpose of the present invention is to solve the above problems and provide a construction safety warning device for project management.

[0007] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0008] The cam is an angular channel that is formed between a pair of camshafts and a pair of camshafts, each of which is adapted to move the camshafts upwards and downwards to move the camshafts upwards. The cam is connected to the support outer cylinder by a shaft, and the two ends of the shaft are connected to the support outer cylinder by a drill bit, and the drill bit passes through the bottom of the support outer cylinder and extends to the outside of the support outer cylinder. The fastener body, the shaft and the drill bit are coaxial and have a through hole with the same diameter inside. A striking hammer body that can be struck downward is arranged on the inner side of the through hole. A spring is sleeved on the outer side of the striking hammer body. The upper end of the spring is fixedly installed with a baffle, and the lower end of the spring is fixedly installed with an annular slider. A cross bar is connected to the two support inner cylinders for common rotation. The two ends of the cross bar are located inside the support inner rod and are provided with two conversion mechanisms that can enable the striking hammer to move up and down.

[0009] Furthermore, the end of the arc-shaped groove is parallel to the elastic substrate, and the elastic substrate is engaged with the position where the supporting inner cylinder is located in the arc-shaped groove.

[0010] Furthermore, an annular groove is provided on the side wall of the shaft rod, the cross-section of the annular groove is semicircular, two symmetrical fixing rods are arranged on both sides of the annular groove, a special-shaped groove corresponding to the fixing rod is provided on the supporting outer cylinder, and the fixing rod is fixedly installed on the position of the supporting outer cylinder in the special-shaped groove, the cross-sections of both ends of the special-shaped groove are circular, the middle cross-section of the special-shaped groove is semicircular, and a complete circle formed by the middle cross-section of the special-shaped groove and the cross-section of the annular groove is the same as the fixing rod.

[0011] Furthermore, each of the conversion mechanisms includes a fixed ring and a connecting rod, two support rods are symmetrically installed on the fixed ring, the fixed ring is fixedly installed on the end of the cross bar, a rotating ring is rotatably connected to one side of the fixed ring on the cross bar, a special-shaped rod is fixedly installed on the rotating ring, an annular slider is fixedly installed on the special-shaped rod, a cylindrical stopper is fixedly installed on the special-shaped rod above the connecting cylinder, the connecting rod is fixedly installed on the connecting cylinder, and the connecting rod is hinged to the striking hammer body.

[0012] Furthermore, the distance between the end of the support rod and the axis of the crossbar is greater than the distance between the near-center end of the cylindrical stopper and the axis of the crossbar and is less than the distance between the near-center end of the connecting cylinder and the axis of the crossbar.

[0013] Furthermore, an integrally formed external stopper is fixedly mounted on the outer side of the bottom of the supporting inner cylinder, and an integrally formed internal stopper is fixedly mounted on the inner side of the top of the supporting outer cylinder, and the cross-sections of the external stopper and the internal stopper are the same.

[0014] Furthermore, an annular light board is fixedly mounted on the outer side of the supporting outer tube, an annular light groove is provided at the bottom of the annular light board, and a plurality of lamp beads evenly arranged along the center of a circle are arranged at the position of the annular light groove on the annular light board.

[0015] Furthermore, the cross-sections of the through holes on the fastener body, the shaft rod and the drill bit are the same, and a sealing disk is fixedly installed on the inner side of the top of the drill bit.

[0016] Furthermore, the bottom end of the striking hammer body is in an inverted cone shape.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The present invention effectively combines the fastening device with the impact hammer system. When the drill bit encounters resistance and cannot be smoothly inserted into the soil, the impact hammer body releases elastic potential energy through the spring to generate impact force, which helps the drill bit to penetrate the hard materials in the soil more easily, thereby solving the problem that ordinary insertion supports are difficult to encounter hard materials to smoothly insert the support rod into the ground to achieve stable support.

[0019] 2. The present invention can maintain the tightness of the warning plate fixing device when vibration occurs through the design of the fastening device, especially the cooperation between the ridge and the slider, thereby preventing loosening caused by long-term vibration and ensuring that the warning device always remains firm.

[0020] In summary, through the coordinated use of the fastening device and the striking hammer system, not only can the support rod be smoothly inserted into the ground when encountering hard materials to achieve stable support, but also the problem of loosening of the support rod due to long-term vibration can be solved, ensuring that the warning device always remains firm.

DETAILED DESCRIPTION

[0035] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] A construction safety warning device for project management according to a preferred embodiment of the present invention will be described in detail below.

[0037] Embodiment 1, as Figure 1 - Fig.13 As shown, a construction safety warning device for project management includes two support rods 1, each support rod 1 includes a support outer cylinder 101 and a support inner cylinder 102 inserted into the support outer cylinder 101, a warning plate 2 is fixedly installed on the upper ends of the two support inner cylinders 102, a rotatable fastening device 3 is arranged inside each support inner cylinder 102, the fastening device 3 includes a fastener body 4 and two adjusting rods 5, the outer side of the fastener body 4 is provided with eight convex ridges 41 evenly arranged along the center of a circle, the cross section of the eight convex ridges 41 is rotated 180 degrees to the right from top to bottom, the convex ridge 41 has a short side 42 on the left and a long side 43 on the right, the short side 42 and the long side 43 have different inclination angles and are evenly arranged along the center of the circle, a baffle 44 is fixedly installed on the top of the fastener body 4, each adjusting rod 5 includes a rectangular elastic base plate 51 and a cylindrical slider 52 fixedly installed in the middle of the elastic base plate 51 and perpendicular to it, the end of the cylindrical slider 52 away from the center of the circle Sliding on the short side 42, the end of the cylindrical slider 52 close to the center of the circle slides on the long side 43, the supporting inner cylinder 102 is provided with an arc groove 6 corresponding to the elastic substrate 51, the bottom of the fastener body 4 is fixedly installed with a shaft rod 7, the shaft rod 7 is rotatably connected to the supporting outer cylinder 101, the bottom of the shaft rod 7 is fixedly installed with a drill bit 8, the drill bit 8 passes through the bottom of the supporting outer cylinder 101 and extends to the outside of the supporting outer cylinder 101, the fastener body 4, the shaft rod 7 and the drill bit 8 are coaxial and each has a through hole 9 with the same diameter, a striking hammer body 10 that can be struck downward is arranged on the inner side of the through hole 9, a spring 11 is sleeved on the outer side of the striking hammer body 10, the upper end of the spring 11 is fixedly installed with the baffle 44, and the lower end of the spring 11 is fixedly installed with an annular slider 14, a cross bar 12 is rotatably connected between the two supporting inner cylinders 102, the two ends of the cross bar 12 are located inside the supporting inner rod and are provided with two conversion mechanisms 13 that can move the striking hammer up and down.

[0038] When it is necessary to install the warning device, the cross bar 12 is rotated, and the cross bar 12 drives the fixing ring 131 to rotate. When the fixing ring 131 rotates, the support rod 137 on the fixing ring 131 will push the cylindrical stopper 135 to drive the connecting cylinder 134 to rotate, thereby driving the end of the connecting rod 136 fixedly connected to the connecting cylinder 134 to perform a circular motion along the center of the cross bar 12, so that the striking hammer body 10 will move up and down reciprocatingly, and the impact force is generated by the power accumulated by the spring 11 to break the hard materials in the soil, so that 8 is easier to insert into the soil.

[0039] When vibration occurs near the warning device, the supporting inner cylinder 102 will reciprocate upward and downward. During the upward movement, the end of the cylindrical slider 52 close to the fastener body 4 will slowly move from the near-center end of the long side 43 to the far-center end of the long side 43 and then enter the adjacent convex ridge 41. During this process, the end of the cylindrical slider 52 close to the fastener body 4 will slowly move from the near-center end of the long side 43 to the far-center end of the long side 43. The distance between the end of the cylindrical slider 52 close to the fastener body 4 and the center of the through hole 9 will become farther and farther. The fastener body 4 will push the cylindrical slider 52 away from the center of the through hole 9. The elastic substrate 51 is elastic, which will squeeze the middle part of the elastic substrate 51 so that the shape of the elastic substrate 51 corresponds to the arc groove 6. When the supporting inner cylinder 102 is downward, the distance between the end of the cylindrical slider 52 close to the fastener body 4 and the center of the through hole 9 will remain unchanged, so that the force applied by the adjusting rod 5 to the convex ridge 41 will push the fastener body 4 to rotate the fastener body 4, so that the drill bit 8 rotates, which can make the drill bit 8 move further downward, solving the problem that the warning device is installed in construction equipment, busy traffic areas, or near mechanical equipment, and long-term vibration and impact will cause the fixing parts of the sign to gradually loosen.

[0040] Embodiment 2

[0041] like Figure 3 As shown, the end of the arc groove 6 is parallel to the elastic substrate 51 , and the elastic substrate 51 is engaged with the position where the supporting inner cylinder 102 is located in the arc groove 6 .

[0042] Embodiment 3

[0043] like Figure 4 - Figure 7As shown, the side wall of the shaft rod 7 is provided with an annular groove 72, the cross-section of the annular groove 72 is semicircular, two symmetrical fixing rods 71 ​​are arranged on both sides of the annular groove 72, and a special-shaped groove 73 corresponding to the fixing rod 71 is provided on the supporting outer cylinder 101. The fixing rod 71 is fixedly installed on the supporting outer cylinder 101 at the position of the special-shaped groove 73. The cross-sections of the two ends of the special-shaped groove 73 are circular, and the middle cross-section of the special-shaped groove 73 is semicircular. The middle cross-section of the special-shaped groove 73 and the cross-section of the annular groove 72 form a complete circle that is the same as the fixing rod 71.

[0044] By providing the fixing rod 71 , the annular groove 72 and the special-shaped groove 73 , the shaft rod 7 can rotate on the fixing rod 71 and the shaft rod 7 will not be separated from the supporting outer cylinder 101 .

[0045] Embodiment 4

[0046] like Fig. 9 - Fig.10 As shown, each conversion mechanism 13 includes a fixed ring 131 and a connecting rod 136. Two supporting rods 137 are symmetrically installed on the fixed ring 131. The fixed ring 131 is fixedly installed at the end of the cross bar 12. A rotating ring 132 is rotatably connected to one side of the fixed ring 131 on the cross bar 12. A special-shaped rod 133 is fixedly installed on the rotating ring 132. The annular slider 14 is fixedly installed on the special-shaped rod 133. A cylindrical stopper 135 is fixedly installed above the connecting cylinder 134 of the special-shaped rod 133. The connecting rod 136 is fixedly installed on the connecting cylinder 134, and the connecting rod 136 is hinged to the striking hammer body 10.

[0047] By rotating the cross bar 12, the cross bar 12 drives the fixing ring 131 to rotate. When the fixing ring 131 rotates, the support rod 137 on the fixing ring 131 will push the cylindrical stopper 135 to drive the connecting cylinder 134 to rotate, thereby driving the end of the connecting rod 136 fixedly connected to the connecting cylinder 134 to perform a circular motion along the center of the cross bar 12, so that the striking hammer body 10 will reciprocate up and down. When the striking hammer body 10 moves upward, it will drive the annular slider 14 to move upward. Since the top of the spring 11 is fixedly installed with the annular slider 14, the annular slider 14 will drive the bottom of the spring 11 to squeeze upward, and the spring 11 accumulates elastic potential energy. When the striking hammer body 10 moves downward, the spring 11 releases the elastic potential energy and hits the hard material in the soil, thereby facilitating the drill bit 8 to continue to be inserted into the soil when it is not easy to insert the drill bit 8 into the soil.

[0048] Furthermore, the distance between the end of the support rod 137 and the axis of the cross bar 12 is greater than the distance between the proximal end of the cylindrical stopper 135 and the axis of the cross bar 12 and is less than the distance between the proximal end of the connecting cylinder 134 and the axis of the cross bar 12 .

[0049] Embodiment 5

[0050] like Fig.12 As shown, an integrally formed external stopper 103 is fixedly mounted on the outer side of the bottom of the supporting inner cylinder 102, and an integrally formed internal stopper 104 is fixedly mounted on the inner side of the top of the supporting outer cylinder 101. The cross sections of the external stopper 103 and the internal stopper 104 are the same.

[0051] Embodiment 6

[0052] like Figure 6 and Fig.13 As shown, an annular light board 15 is fixedly mounted on the outer side of the supporting outer tube 101 , an annular light groove 151 is provided at the bottom of the annular light board 15 , and a plurality of lamp beads 152 evenly arranged along the center of a circle are provided on the annular light board 15 at the position of the annular light groove 151 .

[0053] By setting up multiple lamp beads 152, the drill bit 8 can be easily positioned vertically during the process of being inserted into the soil. When the light projection of the lamp beads 152 on the soil is a perfect circle, it means that the position of the drill bit 8 is vertical, which improves the situation where the drill bit 8 is inserted into the ground at an angle, resulting in the unstable fixation of the warning plate 2.

[0054] Furthermore, the cross-sections of the through hole 9 on the fastener body 4 , the shaft 7 and the drill bit 8 are the same, and a sealing disk 16 is fixedly mounted on the inner side of the top of the drill bit 8 .

[0055] Furthermore, the bottom end of the striking hammer body 10 is in an inverted cone shape.

[0056] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
