DETAILED DESCRIPTION

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear below, they only indicate that the upper, lower, left and right directions are consistent with the accompanying drawings themselves, and do not limit the structure.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Examples, such as Figure 1As shown in FIG. 7 , the safety protection support platform for engineering construction provided by the present invention includes a connecting seat 1, and a guardrail 2 is arranged on the top of the connecting seat 1. Among them, the connecting seat 1 is used to connect with the hydraulic arm of the lifting equipment, and can complete the rotation movement under the control of the lifting equipment. The connecting seat 1 belongs to the prior art and this embodiment will not be repeated here. On this basis, the guardrail 2 provided by the present invention includes a base 21, and the base 21 is provided with a fixed guardrail 22 distributed around the base 21, and the fixed guardrail 22 is provided with an adjustable guardrail 23 that cooperates with the up and down movement thereof. The adjustable guardrail 23 includes a plurality of enclosures 231, and a combination rod 232 is arranged below the enclosure 231. At least one flip armrest assembly 3 is rotatably arranged on the combination rod 232. The flip armrest assembly 3 includes a first bolt 31 for threaded connection with the enclosure 231. The base 21 includes a solid portion 211 located in the middle of the bottom thereof, and grille portions 212 are arranged on both sides of the solid portion 211. The base 21 A five-point buffer 4 is arranged below, and the five-point buffer 4 includes an X-shaped plate 41, and a center hole matching with the connecting seat 1 is arranged in the center of the X-shaped plate 41, and a buffer spring 42 is arranged above the center hole, and the four sides of the X-shaped plate 41 extend in a zigzag shape to the corners close to the grille portion 212, and countersunk holes 43 are arranged at the four ends of the X-shaped plate 41, and support springs 44 are arranged in the countersunk holes 43. A plurality of load-bearing plates 5 arranged in sequence are arranged on the inner side of the base 21, and the load-bearing plates 5 are in a "J" shape. The bottom surface of the load-bearing plate 5 is provided with a dovetail groove 51, and the top surface thereof is provided with a dovetail protrusion 52 for matching with the dovetail grooves 51 of other load-bearing plates 5.

[0026] Specifically, the fence 2 adopts a combination of a fixed guardrail 22 and an adjustable guardrail 23, and can be adjusted in height according to safety protection requirements, so the device has a high utilization rate. In addition to using the enclosure 231 of the adjustable guardrail 23 as a safety handrail, the flip handrail assembly 3 can also be used as another set of more flexible safety handrails, especially after the specific working height inside the fence 2 is fine-tuned, so the safety range of the entire fence 2 is relatively large and more flexible. Regarding the fine-tuning of the working height inside the fence 2, the actual construction height inside the device can be fine-tuned by stacking and plugging multiple detachable load-bearing plates 5 to obtain a more suitable construction height. Further, the base 21 of the device adopts a design of a solid part 211 and a grille part 212. The grille part 212 is supported by an elastic thin plate material, which plays a role in weight reduction on the one hand, and is also less rigid than the whole plate of the same material on the other hand, and is more suitable as a transition piece between the load-bearing plate 5 and the five-point buffer 4. The five stress nodes of the five-point buffer 4 obtain pressure from the grid plate and the load-bearing plate 5, and can effectively absorb and release the potential energy under the action of the buffer spring 42 and the support spring 44, especially when the workers need to walk on the device. Therefore, the device can maintain a good balance under the stimulation of unstable factors, and at the same time improve the connection reliability between the fence 2 and the connecting seat 1 and the hydraulic arm of the lifting equipment.

[0027] In order to improve the combination performance of the fence 2, the fixed guardrail 22 provided by the present invention includes a plurality of hollow lower side posts 221, and the adjustable guardrail 23 includes an upper side post 233 that is plugged into the lower side posts 221 one by one. The lower side posts 221 are provided with second bolts for connecting the lower side posts 221 and the upper side posts 233. The side of the upper side post 233 is provided with two side plates 234 distributed at 90 degrees, and the side plates 234 are connected to the enclosure 231 by third bolts. The second bolt can penetrate and connect the upper side post 233, or it can be inserted from the outside of the lower side post 221 in abutting manner and abut against the outer side of the upper side post 233. At least two threaded holes are provided on the side plate 234 to install the third bolt, thereby connecting the enclosure 231 and the combination rod 232. By changing the actual plug-in depth of the upper side post 233 and the lower side post 221, the actual protection range of the entire fence 2 can be changed. It should be noted that, in addition to the lower side posts 221, the fixed guardrail 22 also includes side panels and other railings connecting adjacent lower side posts 221 to improve the safety level.

[0028] In order to facilitate the assembly of the combined rod 232 and adjust its actual length, the combined rod 232 provided by the present invention adopts a segmented combination design, such as comprising two connecting rods 2321, between which a sleeve 2322 threadedly connected thereto is provided, and the sleeve 2322 is used as a connecting piece of the two connecting rods 2321, and at the same time, an end plate 2323 is provided at the end of the connecting rod 2321, and the end plate 2323 is connected to the side plate 234 and the enclosure 231 by a third bolt. The end plate 2323 and the end of the connecting rod 2321 are welded or connected in other fixed ways, and the flip handrail assembly 3 can be installed on the connecting rod 2321 from the fracture before the combined rod 232 is assembled, and then the two connecting rods 2321 are connected by a sleeve 2322 separately.

[0029] In order to improve the structural stability of the adjustable guardrail 23, the enclosure 231 provided by the present invention is a slot plate with an opening facing downward, and the side plate 234 and the end plate 2323 are both arranged on the inner side thereof. The side plate 234 and the end plate 2323 are both assembled on the inner side of the slot plate in a surrounding form. Compared with the single plate structure, the slot plate has one more supporting surface. The number of connection nodes after the slot plate is connected with the side plate 234 and the end plate 2323 increases, and the top surface of the slot plate is easier to hold if it is used as a handrail. At the same time, designing the enclosure 231 as a slot plate structure is also conducive to improving the reliability of its connection with the flip handrail assembly 3.

[0030] In order to improve the safety of the use of the flip armrest assembly 3, the flip armrest assembly 3 provided by the present invention includes a movable sleeve 32, a grooved plate hoop 33 is provided on the movable sleeve 32, the notch of the plate hoop 33 cooperates with the enclosure 231, a T-shaped handrail 34 is provided on the plate hoop 33, a first bolt 31 is provided on the plate hoop 33, the movable sleeve 32 is provided with variable gaps near both ends thereof, and a locking head 35 is provided on the combination rod 232 that is threadedly connected to the combination rod 232 and the movable sleeve 32. Among them, the notch of the plate hoop 33 can be held on the enclosure 231, there are at least two contact surfaces, the support effect is good and the anti-deformation ability is strong, so the use safety is high. Furthermore, by adjusting the fitting depth of the locking head 35 on the combination rod 232 and the movable sleeve 32, the diameter of the variable gap can be directly changed, thereby changing the actual diameter of the movable sleeve 32, that is, the combination rod 232 can be clamped without flipping; and because the locking sleeve is threadedly connected to the combination rod 232 and the movable sleeve 32 at the same time, the axial position of the flip armrest assembly 3 on the combination rod 232 will not move arbitrarily.

[0031] In order to improve the utilization rate of the support spring 44, the support spring 44 provided by the present invention includes a disc-shaped piece 441, a support body 442 is provided at the bottom of the disc-shaped piece 441, the support body 442 is matched with the countersunk hole 43, a clamping joint 443 is provided at the bottom of the support body 442, and the clamping joint 443 is clamped and matched with the end of the X-shaped plate 41. The bottom surface of the clamping joint 443 is an inverted cone surface to facilitate penetration into the countersunk hole 43, and the support spring 44 is inserted into the countersunk hole 43 from the outside to the inside until the clamping joint 443 is clamped on the other side of the countersunk hole 43, the radial stability of the support spring 44 is ensured by the support body 442, and the pressure from the grille part 212 and the load-bearing plate 5 is carried by the disc-shaped piece 441.

[0032] In order to improve the safety of the device, the load-bearing plate 5 provided by the present invention is made of plastic material, and a plurality of structural holes 53 are provided inside the load-bearing plate 5 to penetrate the front and back. The load-bearing plate 5 is light in weight and can be directly disassembled and stacked by a single person on site, so as to adjust its actual working height inside the device. The plug-in design of the dovetail groove and the dovetail protrusion can improve the integrity and stability of different load-bearing plates after stacking.
