Description

Technical Field

[0001] This utility model relates to the field of protective device technology, and in particular to a protective device for blasting operations. Background Technology

[0002] Blasting is a technique that utilizes the compression, loosening, destruction, throwing, and destructive effects produced by the explosion of explosives in air, water, soil, rock, or other objects to achieve a desired objective. When an explosive charge or package detonates in soil, rock, or a structure, it causes compression, deformation, destruction, loosening, and throwing of the material. Blasting is primarily used in earthwork engineering and the demolition of metal buildings and structures.

[0003] In existing technologies, protective devices are generally used during blasting operations. However, the existing protective devices are generally simple in structure, and the protective plates usually do not have buffer devices. This allows the impact force generated by the blast and the debris to act directly on the protective device, resulting in a large impact force and reducing the comfort of people using the protective device. In addition, existing protective devices are usually equipped with casters to ensure easy movement, but there are no devices to position the device when placing it. This allows the impact force generated by the blast to act directly on the device, and people still need to stop the device, otherwise it will move. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies. By moving the connecting plate, the moving ring is moved, thereby placing the support ring at the lower end of the moving ring with the placement location. The impact force generated by the blast is offset by the friction between the anti-slip plate at the lower end of the support ring and the ground, thus preventing the device from moving due to excessive impact force. This invention provides a protective device for blasting operations.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A protective device for blasting operations includes a base with multiple symmetrically arranged casters at the lower end, a baffle at the upper end of the base, a top plate at the upper end of the baffle, a buffer plate in front of the baffle, the buffer plate being made of rubber, a connecting mechanism for connecting the buffer plate at the front end of the baffle, a movable ring on the outside of the base, a support ring at the lower end of the movable ring, an anti-slip plate at the lower end of the support ring, and a moving mechanism for moving the movable ring inside the base.

[0007] Preferably, the connecting mechanism includes a plurality of telescopic rods symmetrically arranged on the inner wall of the buffer plate, and the fixed ends of the plurality of telescopic rods are provided with a mounting plate, which is located at the front end of the baffle.

[0008] Preferably, the moving mechanism includes multiple through slots formed between multiple inner and outer walls of the base, and a connecting plate is slidably connected between the multiple through slots. The connecting plate is cross-shaped, and multiple ends of the connecting plate are respectively connected to multiple inner walls of the moving ring.

[0009] Preferably, a power motor is provided at the upper end of the base, and a threaded rod is rotatably connected inside the base. The threaded rod passes through the connecting plate and is threadedly connected to it. The upper end of the threaded rod passes through the upper end of the rotating base and is connected to the end of the output shaft of the power motor.

[0010] Preferably, the buffer plate and the mounting plate are elastically connected by multiple springs, and the multiple springs are respectively sleeved on the outer wall of the telescopic rod.

[0011] Preferably, each of the plurality of through slots is provided with a guide rod, and the plurality of guide rods pass through the connecting plate and are slidably connected thereto.

[0012] The beneficial effects of this utility model are:

[0013] 1. By moving the connecting plate, the moving ring is moved, thereby placing the support ring at the lower end of the moving ring with the placement location. The friction between the anti-slip plate at the lower end of the support ring and the ground is used to offset the impact force generated by the explosion, preventing the device from moving due to excessive impact force.

[0014] 2. By setting up a buffer plate in front of the baffle, the debris generated by the blasting acts directly on the buffer plate, avoiding the debris from acting directly on the baffle, which would result in a larger impact force between the baffle and the entire device, reducing the comfort of users.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Reference Figure 1-3 A protective device for blasting operations includes a base 1, with multiple symmetrically arranged casters 12 at the lower end of the base 1, a baffle 4 at the upper end of the base 1, a top plate 5 at the upper end of the baffle 4, and a buffer plate 9 in front of the baffle 4. The buffer plate 9 is made of rubber. A connecting mechanism for connecting the buffer plate 9 is provided at the front end of the baffle 4. The connecting mechanism includes multiple symmetrically arranged telescopic rods 7 on the inner wall of the buffer plate 9. The fixed ends of the multiple telescopic rods 7 are all provided with a mounting plate 6. The mounting plate 6 is located at the front end of the baffle 4. By setting the buffer plate 9 in front of the baffle 4, the debris generated by blasting acts directly on the buffer plate 9, avoiding the debris from directly acting on the baffle 4, which would cause the baffle 4 and the entire device to bear a large impact force, thereby reducing the comfort of people using the device.

[0022] The base 1 has a movable ring 2 on its outside, a support ring 3 at the lower end of the movable ring 2, and an anti-slip plate 11 at the lower end of the support ring 3. The base 1 has a moving mechanism for moving the movable ring 2. The moving mechanism includes multiple through slots 13 formed between multiple inner and outer walls of the base 1. A connecting plate 15 is slidably connected between the multiple through slots 13. The connecting plate 15 is cross-shaped. Multiple ends of the connecting plate 15 are connected to multiple inner walls of the movable ring 2. By moving the connecting plate 15, the movable ring 2 is moved, thereby placing the support ring 3 at the lower end of the movable ring 2 with the placement position. The friction between the anti-slip plate 11 at the lower end of the support ring 3 and the ground is used to offset the impact force generated by the explosion, preventing the device from moving due to excessive impact force.

[0023] A power motor 10 is provided on the upper end of the base 1. A threaded rod 16 is rotatably connected inside the base 1. The threaded rod 16 passes through the connecting plate 15 and is threadedly connected to it. The upper end of the threaded rod 16 passes through the upper end of the rotating base 1 and is connected to the end of the output shaft of the power motor 10.

[0024] The buffer plate 9 and the mounting plate 6 are elastically connected by multiple springs 8, and the multiple springs 8 are respectively sleeved on the outer wall of the telescopic rod 7.

[0025] Each of the multiple through slots 13 is provided with a guide rod 14, and the multiple guide rods 14 pass through the connecting plate 15 and are slidably connected to it.

[0026] When using this utility model, the protective device is placed at the designated location, and the power motor 10 is started. The power motor 10 drives the threaded rod 16 to rotate. The threaded connection between the threaded rod 16 and the connecting plate 15, as well as the guiding action of multiple guide rods 14 on the connecting plate 15, causes the connecting plate 15 to move, which in turn moves the moving ring 2. This allows the support ring 3 at the lower end of the moving ring 2 to be placed at the designated location. The friction between the anti-slip plate 11 at the lower end of the support ring 3 and the ground helps to offset the impact force generated by the explosion, preventing the device from moving due to excessive impact force.

[0027] By setting the buffer plate 9 in front of the baffle 4, the blasted debris acts directly on the buffer plate 9, avoiding the debris from directly impacting the baffle 4 and causing the baffle 4 to deform. Furthermore, through the elastic action of the spring 8 between the buffer plate 9 and the mounting plate 6, as well as the extension and retraction action of the telescopic rod 7, multiple springs 8 buffer the impact force brought by the debris, thereby improving the service life of the device.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
