Description

Technical Field

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

[0002] Engineering blasting, as a scientific technology, has a wide range of applications, but its most important and common use is in engineering. It's used in mining, tunneling for railways and highways, water conservancy projects, and even in urban areas for building demolition. Utilizing the enormous energy generated by explosives to destroy the original structure of an object creates a destructive effect that cannot be replicated by other methods. While it doesn't independently complete a project, it is a crucial step in the process.

[0003] like Figure 4 The image shows a previous generation of blasting pipe fixing device used in engineering blasting. Its main function is to limit and fix the blasting pipe within the blast hole, preventing displacement and slippage of the blasting pipe during installation and blasting, thereby improving the safety and stability of actual engineering blasting operations. However, this type of blasting pipe fixing device has the following shortcomings in actual use: The previous generation fixing device is an integrated structure, with the support rod fixed to the fixing plate, and the fixing clamp for fixing the blasting pipe fixed to the lower end of the support rod. This means that fixing devices of corresponding specifications must be used for fixing blasting pipes of different lengths and diameters. At the same time, when fixing the blasting pipe, operators need to use tools, fasteners, and shims. The entire blasting pipe fixing operation is inconvenient and inefficient, increasing the workload and difficulty of actual engineering blasting operations.

[0004] In view of this, it is particularly important to design and manufacture a blasting pipe fixing device that can adjust and fix blasting pipes of different lengths and diameters without tools, and to apply it in engineering blasting processes. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of the previous generation of blasting pipe fixing devices for engineering blasting, which required customization according to the specifications of the blasting pipe and had poor convenience and low efficiency in fixing the blasting pipe. Therefore, a new blasting pipe fixing device for engineering blasting is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for fixing blasting pipes used in engineering blasting includes a fixing plate, two support rods symmetrically arranged at the lower end of the fixing plate, and a fixing ring fixed at the lower end of the two support rods. The two support rods are movably mounted on the fixing plate through a sliding adjustment part. The fixing ring is provided with a pressure locking mechanism that can be used for tool-free internal pressure fixing of blasting pipes of different diameters.

[0008] As a further description of the above technical solution:

[0009] The locking mechanism includes multiple T-shaped sliding holes equally spaced on the fixed ring, a fixed block movably installed inside the multiple T-shaped sliding holes, multiple one-way locking blocks symmetrically fixed on both sides of the fixed block, and one-way locking grooves opened inside the T-shaped sliding holes and corresponding to the positions of the multiple one-way locking blocks.

[0010] As a further description of the above technical solution:

[0011] The cross-sections of the multiple one-way locking blocks and the T-shaped sliding holes are all right-angled triangular structures, and the right-angled portions of the one-way locking blocks and the T-shaped sliding holes are set towards the outer end of the fixed block.

[0012] As a further description of the above technical solution:

[0013] The fixing block has vertically distributed through holes in its middle.

[0014] As a further description of the above technical solution:

[0015] A pressing block is fixedly connected to the outer end of the fixing block.

[0016] As a further description of the above technical solution:

[0017] The sliding adjustment part includes a guide sleeve symmetrically fixed on the fixed plate and corresponding to the positions of the two support rods, a damping slide cylinder vertically fixed in the middle of the guide sleeve, a limiting post movably installed inside the damping slide cylinder and penetrating the support rod, and multiple limiting holes equidistantly opened on the support rod and transitionally fitted with the limiting post.

[0018] As a further description of the above technical solution:

[0019] A handle is integrally fixed to the outer end of the limiting post.

[0020] As a further description of the above technical solution:

[0021] Fixed ribs are rotatably installed at the four corners of the fixed plate, and mounting holes are provided on the fixed ribs.

[0022] As a further description of the above technical solution:

[0023] Multiple anti-deviation blocks arranged in a circular array are fixedly connected to both the upper and lower ends of the fixed block.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0025] 1. In this utility model, the original integrated fixing device is improved into a split structure. A fixing ring, a T-shaped sliding hole, a one-way locking groove, a fixing block, a one-way locking block, and a pressing block are set at the lower end of the two support rods. After the rupture tube is adjusted and placed into the fixing ring, the fixing block can be inserted into the T-shaped sliding hole of the fixing ring. At this time, under the anti-reverse locking action between the one-way locking block and the one-way locking groove, the inner ends of multiple fixing blocks can contact and press against the outer wall of the rupture tube, locking the rupture tube in the fixing ring. This structure can realize tool-free internal pressure fixing operation for rupture tubes of different diameters, effectively reducing the workload and difficulty of rupture tube fixing operation, thereby improving the convenience and efficiency of rupture tube fixing operation.

[0026] 2. In this utility model, a guide sleeve, a damping cylinder, and a limiting post are provided on the fixed plate, and multiple limiting holes are provided on the support rod. The support rod can be adjusted within the guide sleeve. After the distance between the fixed plate and the fixed ring is adjusted, the limiting post can be inserted into the limiting hole at the designated position of the damping cylinder and the support rod. At this time, the distance between the fixed plate and the fixed ring can be locked. This structure allows for adjustment of the distance between the fixed plate and the fixed ring according to the actual fixing requirements of blasting tubes of different lengths, further improving the convenience and efficiency of blasting tube fixing operations, and also enhancing the applicability of the fixing device.

[0033] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-4 This utility model provides a technical solution: a blasting pipe fixing device for engineering blasting, including a fixing plate 1, two support rods 2 symmetrically arranged at the lower end of the fixing plate 1, and a fixing ring 3 fixed at the lower end of the two support rods 2. The two support rods 2 are movably installed on the fixing plate 1 through a sliding adjustment part. The fixing ring 3 is provided with a pressure locking mechanism that can be used for tool-free internal pressure fixing operation of blasting pipes of different diameters.

[0035] Specifically, such as Figure 1-3 As shown, the locking mechanism includes multiple T-shaped sliding holes 301 that are equally spaced on the fixed ring 3, a fixed block 4 that is movably installed inside the multiple T-shaped sliding holes 301, multiple one-way locking blocks 401 that are symmetrically fixed on both sides of the fixed block 4, and one-way locking grooves 302 that are opened inside the T-shaped sliding holes 301 and correspond to the positions of the multiple one-way locking blocks 401.

[0036] Among them, the cross-sections of multiple one-way locking blocks 401 and T-shaped sliding holes 301 are all right-angled triangular structures. The right-angled parts of the one-way locking blocks 401 and T-shaped sliding holes 301 are set towards the outer end of the fixing block 4, which allows the fixing block 4 to move inward in one direction within the T-shaped sliding hole 301, and prevents the fixing block 4 from moving outward within the T-shaped sliding hole 301, thereby achieving the effect of anti-retrieval locking.

[0037] Meanwhile, a vertically distributed through hole 402 is provided in the middle of the fixing block 4, and a pressing block 403 is fixedly connected to the outer end of the fixing block 4, which can increase the contact area of ​​the outer end of the fixing block 4 and make it convenient for the operator to press the fixing block 4 inward and fix it into the T-shaped sliding hole 301.

[0038] Specifically, such as Figure 1 and Figure 2As shown, the sliding adjustment part includes a guide sleeve 101 symmetrically fixed on the fixed plate 1 and corresponding to the positions of the two support rods 2, a damping sleeve 102 vertically fixed in the middle of the guide sleeve 101, a limiting post 5 movably installed inside the damping sleeve 102 and penetrating the support rod 2, and multiple limiting holes 201 equidistantly opened on the support rod 2 and transitionally fitted with the limiting post 5. The damping sleeve 102 is made of vulcanized rubber material. When the limiting post 5 contacts the damping sleeve 102, it can generate a certain sliding damping to prevent the limiting post 5 from sliding away from the guide sleeve 101 and the limiting hole 201 of the support rod 2 under force. The outer end of the limiting post 5 is integrally fixedly connected to a handle 501, which facilitates the operator to hold the outer end of the limiting post 5 and perform sliding adjustment operations.

[0039] Specifically, such as Figure 1 and Figure 2 As shown, a fixing rib 103 is rotatably installed at each of the four corners of the fixing plate 1. The fixing rib 103 has a mounting hole 104. The rotatable fixing rib 103 makes it easy for the fixing plate 1 to be fixed to the outside of the blast hole by adjusting it in multiple directions with fasteners.

[0040] Specifically, such as Figure 1-3 As shown, multiple anti-deviation blocks 303 arranged in a ring array are fixedly connected to the upper and lower ends of the fixing block 4, which facilitates the blasting tube to slide into the inner side of the fixing block 4. At the same time, it can perform lateral anti-deviation support operation on the blasting tube to ensure that the blasting tube can be coaxially distributed with the fixing plate 1 and the fixing ring 3.

[0041] Working principle: During use, when fixing the blasting tube, firstly, the operator adjusts the distance between the fixing plate 1 and the fixing ring 3 according to the actual blasting pre-embedding requirements and the length of the blasting tube. The limiting post 5 is slid outwards away from the damping slide cylinder 102 on the guide sleeve 101, allowing the support rod 2 to slide and adjust within the guide sleeve 101. After the distance between the fixing plate 1 and the fixing ring 3 is adjusted, the limiting post 5 is slid inwards through the damping slide cylinder 102 into the limiting hole 201 at the designated position on the support rod 2. At this point, the distance between the fixing plate 1 and the fixing ring 3 is locked. Next, the blasting tube is adjusted and placed into the fixing ring 3. Then, take the fixing block 4 and slide its head into the T-shaped sliding hole 301. When the fixing block 4 slides into the T-shaped sliding hole 301, the one-way locking block 401 on the fixing block 4 can contact the one-way locking groove 302 on the inner side of the T-shaped sliding hole 301. Under the anti-reverse locking action between the one-way locking block 401 and the one-way locking groove 302, the inner ends of multiple fixing blocks 4 can contact and press against the outer wall of the blasting tube, locking the blasting tube in the fixing ring 3. Finally, insert the blasting tube and the fixing device into the blast hole, and then use the fixing rib plate 103 and fasteners to fix the fixing plate 1 to the outside of the blast hole. The fixing operation of the blasting tube is completed, and the subsequent blasting operation can be carried out.

[0042] 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.
