Description

Technical Field

[0001] This utility model relates to the field of building demolition blasting protection technology, specifically a portable, assembled building demolition blasting protection device. Background Technology

[0002] Building demolition blasting protection is a complex and high-risk task. Before demolition, a detailed investigation of the building's structural strength and surrounding environment must be conducted, and a targeted blasting plan must be developed. Warning signs and protective devices must be set up around the blasting area to prevent unauthorized personnel from entering and to ensure construction safety.

[0003] For example, patent CN215373732U discloses a blasting protection device for building demolition, including a first column, a second column on one side of the first column, and two vertical slots on both the first and second columns. Within each vertical slot, from top to bottom, are arranged a top rail, multiple energy storage rails, and a bottom rail. A first through slot is formed at the bottom of the top rail, and a second through slot is formed on the side wall of the top rail. A pressure relief plate for the top rail is installed within the second through slot, and a guide plate for the top rail is installed inside the top rail. Through the use of latex sheets, the device effectively collects the energy of the shock wave generated by the blast impact and compression of the surrounding air, and allows the energy of the shock wave to be released slowly. The setup of top railings, bottom railings, multiple energy storage railings, and vertical slots makes equipment assembly and disassembly very convenient. Demolition blasting areas of buildings require complete enclosure for protection, and the protection range is relatively large. Protective devices are typically designed as modular structures for easy assembly and transport. However, the terrain of some demolition areas is irregular, requiring adjustment of the connection angles during assembly. Existing protective devices often have relatively simple assembly and connection methods, making flexible adjustment difficult. Furthermore, while protective devices are generally installed high, their stability is limited, making them prone to loosening or tipping over under the impact of demolition blasts, hindering stable installation and use.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing building demolition blasting protection devices. Summary of the Invention

[0005] The purpose of this utility model is to provide a portable, modular building demolition blasting protection device to solve the problems mentioned in the background art, such as the irregular terrain of some demolition areas, the need to adjust the connection angle when assembling the protection device, and the relatively simple assembly and connection methods of some existing protection devices, which are not convenient for flexible adjustment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable, modular building demolition blasting protection device, comprising a support frame fixed to the ground by bolts, a protective cover plate for protecting against building demolition blasting operations fixed on the support frame, reinforcing ribs for increasing overall strength fixedly installed on the protective cover plate, a main mounting frame fixedly installed on one side of the protective cover plate, and a secondary mounting frame installed on the other side of the protective cover plate, with a quick-assembly assembly mechanism provided between the main mounting frame and the secondary mounting frame; and a folding support mechanism for reinforcing its installation on the ground is provided on the protective cover plate.

[0007] Preferably, the assembly mechanism includes a guide column fixed on the sub-mounting frame, an internal round rod fixedly connected inside the guide column along the axial direction, and a movable round rod slidably sleeved on the outside of the internal round rod; the movable round rod is slidably connected through the guide column, and its movable round rod is engaged with the main mounting frame.

[0008] Preferably, the guide post is provided with a sliding groove, and a sliding ring frame is slidably connected to the sliding groove, and the sliding ring frame is fixedly connected to the movable round rod.

[0009] Preferably, a limiting spring is elastically connected between the inner side of the guide post and the movable round rod, and the limiting spring is elastically sleeved on the outside of the built-in round rod.

[0010] Preferably, a circular seat is fixedly installed on the main mounting frame, and multiple retaining strips are fixed at equal angles on the inner side wall of the circular seat; multiple retaining grooves are opened at equal angles on the outer side of the guide post, and the guide post is installed on the inner side of the multiple retaining strips distributed in a ring through the retaining grooves.

[0011] Preferably, the folding support mechanism includes a fixed frame fixed to the protective cover plate, and a support leg is rotatably mounted on the fixed frame.

[0012] Preferably, a slide rail is fixedly installed on the protective cover plate, a slide block is slidably connected on the slide rail, and a support rod is rotatably connected on the slide block; a positioning seat is fixedly installed on the support bracket, and the positioning seat is rotatably connected to the support rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the portable assembled building demolition blasting protection device uses a support frame to erect and fix the protective cover plate on the ground, and arranges and combines multiple protective cover plates through the main mounting frame and the auxiliary mounting frame to protect the building demolition blasting area over a large area.

[0014] Furthermore, a quick-assembly assembly mechanism is provided between the main mounting bracket and the auxiliary mounting bracket. The main mounting bracket and the auxiliary mounting bracket are distributed correspondingly on two adjacent protective cover plates. The movable round rod on the auxiliary mounting bracket is engaged and installed on the main mounting bracket, which can realize the quick assembly of the two protective cover plates.

[0015] Based on the terrain of the building demolition blasting area, the angle between two adjacent protective cover plates is adjusted to control the rotation of the guide column through the main mounting frame. After rotation, the guide column is connected to the ring seat through the slot and the strip, thus limiting its rotation angle.

[0016] Furthermore, the protective cover is equipped with a foldable support mechanism to reinforce its installation on the ground. After the protective cover is installed, the support legs are controlled to rotate downwards and fit against the ground, and the support legs are fixed to the ground with bolts to improve the stability of the protective cover installation.

[0017] During the rotation and unfolding of the support legs, the support rod connects the slide and the support legs and rotates and unfolds. The support rod is tilted and supported on the side of the protective cover, which can improve the support strength of the protective cover installation, improve its impact resistance, and further improve the stability of the protective device installation and application.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: Please refer to Figures 1-8 The present invention provides the following technical solution: a portable assembled building demolition blasting protection device, including a support frame 1 fixed to the ground by bolts, a protective cover plate 2 for protecting building demolition blasting construction fixed on the support frame 1, a reinforcing rib 3 for increasing the overall strength fixedly installed on the protective cover plate 2, a main mounting frame 4 fixedly installed on one side of the protective cover plate 2, and a secondary mounting frame 5 installed on the other side of the protective cover plate 2, and a quick assembly mechanism is provided between the main mounting frame 4 and the secondary mounting frame 5.

[0029] The assembly mechanism includes a guide post 6 fixed on the sub-mounting frame 5. An internal round rod 7 is fixedly connected inside the guide post 6 along the axial direction, and a movable round rod 8 is slidably sleeved on the outside of the internal round rod 7. The movable round rod 8 is slidably connected through the guide post 6 and is engaged with the main mounting frame 4.

[0030] The guide post 6 has a sliding groove 9, and a sliding ring frame 10 is slidably connected to the sliding groove 9. The sliding ring frame 10 is fixedly connected to the movable round rod 8.

[0031] A limiting spring 11 is elastically connected between the inner side of the guide post 6 and the movable round rod 8, and the limiting spring 11 is elastically sleeved on the outside of the built-in round rod 7.

[0032] A circular seat 12 is fixedly installed on the main mounting bracket 4. Multiple retaining strips 13 are fixed at equal angles on the inner side wall of the circular seat 12. Multiple retaining grooves 14 are opened at equal angles on the outer side of the guide post 6. The guide post 6 is engaged with the multiple retaining strips 13 distributed in a ring through the retaining grooves 14.

[0033] Multiple protective covers 2 can be combined and installed to form a large protective area. Each protective cover 2 is small in size and easy to move and transport. When installing two sets of protective covers 2, the main mounting bracket 4 and the auxiliary mounting bracket 5 on the two adjacent protective covers 2 are positioned to correspond to each other. The control slip ring 10 moves along the direction of the slide groove 9. The slip ring 10 moves the moving round rod 8 synchronously, so that the moving round rod 8 moves into the interior of the guide column 6 first. At this time, the moving round rod 8 compresses the limit spring 11, controlling the moving round rod 8 to correspond to the position of the main mounting bracket 4. Then the slip ring 10 is released. At this time, the limit spring 11 is released elastically, pushing the moving round rod 8 and the slip ring 10 to move. The built-in round rod 7 moves and engages into the main mounting bracket 4, so that the two adjacent protective covers 2 can be quickly assembled.

[0034] Based on the terrain of the blast protection area, the assembly angle between two adjacent protective cover plates 2 is adjusted. The moving ring frame 10 drives the moving rod 8 to move away from the main mounting frame 4, and the corresponding angle between the main mounting frame 4 and the auxiliary mounting frame 5 is adjusted. After the moving rod 8 is released, the slot 14 on the moving rod 8 engages with the locking strip 13 inside the ring seat 12, which restricts the assembly angle of the two protective cover plates 2 at this time, so that the protective cover plates 2 can be assembled flexibly.

[0035] Example 2: Based on Example 1, a folding support mechanism is also disclosed, the specific structure of which is as follows: a folding support mechanism is provided on the protective cover plate 2 to reinforce its installation on the ground; the folding support mechanism includes a fixed frame 15 fixed on the protective cover plate 2, and a support leg 16 is rotatably installed on the fixed frame 15.

[0036] A slide rail 17 is fixedly installed on the protective cover plate 2. A slide seat 18 is slidably connected to the slide rail 17. A support rod 19 is rotatably connected to the slide seat 18. A positioning seat 20 is fixedly installed on the support bracket 16. The positioning seat 20 is rotatably connected to the support rod 19.

[0037] The support frame 1 is fixed to the ground with bolts, so that the protective cover plate 2 is initially fixed on the ground. Then, the support leg 16 is rotated and fitted to the ground, and the support leg 16 is fixed to the ground with bolts. During the rotation and unfolding of the support leg 16, the support rod 19 is connected between the support leg 16 and the slide 18 and rotates and unfolds. The support rod 19 pushes the slide 18 to engage with the slide rail 17 and slide. The support rod 19 is inclined and supports the side of the protective cover plate 2, which improves the impact resistance of the protective cover plate 2 on the ground and improves the stability of the assembly and application of the protective cover plate 2.
